Talk about a multi-tasker! Sous vide technology can make eggs to any doneness, incubate yogurt, pasteurize yolks (as for mayonnaise), poach fruit, cook vegetables, thaw frozen food quickly and without any of the issues of a microwave, and, let’s not forget, create the most perfectly done proteins on the planet (steak, fish, pork butt, ribs, even hamburgers). All you need is a pot of water, a bag of food, and a creative imagination.
Sous vide cooking just keeps getting better. Costs have come down, designs have gotten more streamlined, and the add-ons, like WiFi and Bluetooth, have brought sous vide cooking to a whole new level of fun (if you go for that sort of thing).
But more than that, all these new products on the market mean that sous vide is ketchin’ on! Because sous vide is such a truly excellent way to cook, and such an easy-to-use, no-muss-no-fuss kitchen tool, all home cooks should discover its wonders.
Here, we review the best sous vide products on the market: the most popular immersion circulators and the techno-geek high-end circulators.
Our recommendations are based on a background in engineering and chemistry, many, many hours of hands-on research, and years of experience cooking with sous vide.
If you’ve researched sous vide, are excited about the possibilities, and have decided to take the plunge (yes, that is meant to be a bad sous vide pun), then you’re ready to look at the available products.

What Factors Are Important In Choosing a Sous Vide Circulator or Water Oven?
As with any product, it’s important to get past all the marketing jargon and know what to look for. If you are new to sous vide, it’s even more important. These are the important factors to think about.
Immersion Circulator Vs Water Bath: What’s the Difference?
An immersion circulator is a pump you can attach to any vessel. It has a computer-controlled temperature sensor that measures and heats/cools the water while circulating it to keep it at a constant temperature.
A water oven is a self-contained heater-and-vessel unit. They have a computer-controlled temperature sensor and an insulated cooking area. Most water ovens rely on convection currents to equilibrate temperature (no pump). Because they don’t circulate the water, they are more prone to hot and cold spots, but are still considered to be very accurate.
Ability to Hold Temperature
Above all, the best sous vide products need to hold a constant temperature because this is the whole point: the constant temp is what makes it impossible to overcook a steak, cook eggs to the exact degree of doneness you desire, and perform countless other precision temperature tasks.
The truth is, most sous vide products do this very well. Some, like the PolyScience, are as precise as laboratory equipment and can hold a temperature to within a hundredth of a degree (impressive, huh?). But that's not really necessary. Plus or minus one degree is all the accuracy required for kitchen use.
The only exception to this is if you want to hold a temperature constant when very close to the danger zone. Most bacteria grows between 40F and 130F (the danger zone), so if you want to cook food at 131F, a large temperature fluctuation (i.e., greater than 1 degree Fahrenheit) could mean the difference between deliciousness and food poisoning. Since medium-rare steak has an internal temp of about 130F, this can be a real concern that you have to be aware of and if you're sous-viding at this temperature, be sure to not leave the food in the water bath for more than two hours.
Power, measured in wattage, is also an important consideration. First of all, all of these units are standard 120VAC units, which mean they plug into a standard wall outlet and have a maximum power of 1800 watts. None of the circulators or water ovens we review here actually go that high; the average is around 1000 watts.
Higher power doesn’t necessarily make one sous vide unit better than another one. What more power does do is increase the rate at which the circulator comes up to temperature. This means that a circulator with more power (higher wattage) will reach temperature faster. And the differences in speed is actually quite large.
A circulator with 1100W is, surprisingly, a lot faster than a circulator with 900W. While results will vary based on several factors--initial water temp, amount of water, the set temp you're going for--the 1100W circulator can be almost twice as fast as the lower powered one. If you're starting from frozen when you get home from work, this can make a big difference in how quickly you can get a meal on the table.
All the best sous vide options are pretty easy to use, but there are differences. Some displays are larger than others; some show both the setpoint and the current temp and some don’t; some are read from the top, some are read from an angle; and some are easier to set than others. We describe all controls and give pros and cons so you can choose the one that best fits your style and preferences.
Sous vide circulators overall are pretty quiet. Most of them make a quiet hum slightly louder than a computer fan (unless there’s something wrong, like a low water level). So unless you are very sensitive, regular operating noise shouldn’t be an issue. Water baths are even quieter because they don’t have a pump.
More important might be the beeps and alerts the unit makes to let you know what it’s doing. Some beep when they reach temp, some don’t. Most will beep before shutting off if there’s a problem (such as a low water level), but not all of them.
You get to know the sounds and what they mean. They are generally quick and helpful, and not too annoying.
Aesthetics (How does it feel? Do I like its looks? Is it easy to store?)
“Aesthetics” refers to the design of the circulator: heft, solidity, and overall look and feel. The best sous vide circulator or water oven for you should appeal not only to your practical side, but should also be a joy to use.
People tend to underestimate the aesthetics of things, but aesthetics are important. This article on wooden spoons is an interesting summary of the importance of aesthetics in everyday life.
You may think that aesthetics in everyday objects is unimportant, but I would argue that aesthetics are the most important in everyday objects. Because you use them every day! Cheap, crappy objects add to life’s drudgery. But everyday objects that have a nice heft, pleasurable feel, and are pleasing to your eye can make daily chores feel almost luxurious. Filling your kitchen with beautiful tools adds pleasure to your life.
The good news with immersion circulators is that you don’t need to spend a ton of money to get a product with really nice aesthetics. (Water ovens, however, can cost a bit more.)
Update: When this article was written, the Joule wasn't on the market yet. The Joule, with its minimalist design and impressive operating features, blows every other circulator out of the water in the aesthetics category (including the high-end PolyScience circulators). The designers have really thought of everything. For more info, see our review of the Joule.
Ease of Cleaning and Storage
Overall, both sous vide circulators and sous vide water ovens are low maintenance appliances. Some circulators have a removable housing for easy cleaning and some don't, so be sure to get one that comes apart if this is important to you. It's rare to get food particles inside a circulator, though bags can break and make an occasional mess. The circulating aspect of the machine tends to clean itself out pretty well, though.
Water ovens are even easier to maintain: they're just big tubs, so very easy to clean. If you leave them full of water without regular use, they can grow bacteria, and it can be a bit of a pain to empty them every time you use them. But other than that, maintenance is minimal.
Storage space might well dictate which sous vide technology you decide to go with. If you want something small and compact that you can put in a drawer when you're not using it, then your best sous vide choice is a circulator. If you have a lot of counter space and/or storage space, a water oven might be the ticket. As with any appliance purchase, remember to take these factors into consideration.
How much do you want to spend? The “new generation” circulators have come down in price a lot, and you can find them for around $50 now. You can spend several hundred, though, if you want a laboratory-precision instrument.
Water ovens are bigger and generally more expensive, but you can find them under $100 now.
Capacity refers to the amount of water a sous vide immersion circulator can efficiently heat. For most, this is around 5 gallons, which should be more than enough for most home cooks (even if doing a pork butt or turkey in a cooler).
The capacity rating of a circulator isn’t all that important because it doesn’t really tell you very much. First of all, because you’re rarely going to need to use more than 5 gallons of water. But also because many factors affect a unit’s “capacity” such as the ambient air temp, how much food is being put in the water, whether the container is covered, etc. So don’t worry too much about it.
And of course, this is a non-issue with the water ovens, which have a set capacity, usually between 2 and 3 gallons, which is enough to do several steaks, a roast, or a chicken.
Some models have timers and some don’t, and some of the timers just let you know when a cooking time has elapsed and keep running, while some timers turn the unit off.
You don't really need a timer, and using one kind of misses the point of sous vide cooking, and what makes it so great. Because the purpose of sous vide, as Nathan Myhrvold so eloquently put it, is to "free cooks from the tyranny of the clock." If you forget about a steak, it’s not going to get overdone; the water bath will simply hold it at 135F until you’re ready to take it out. You don’t want to test this by leaving it in there overnight (the texture will change), but an hour or two (or three) is just fine.
Of course, there are some sous vide applications that require precise cooking times. Fruit and vegetables, for example--if you let them go too long, they’ll turn to mush. So yes, a timer on your sous vide machine can be useful, especially if it turns the circulator off when done.
As sous vide grows in popularity, different schools of thought evolve on how to use it. So if a timer is important to you--most crucially, if you want the sous vide machine to switch off when the cooking time is up--then be sure to get a model with a timer. But consider the fact that sous vide's precise temperatures allow you to be imprecise with cooking time (for most things, anyway). You can err an hour or two past the finish point, and will still have a delicious meal waiting for you.
How great is that??
A few models--most notably, the Anova--now offer Internet connectivity, including both WiFi and Bluetooth. You have to download a free app to use it, but once you have it, you can control your device remotely.
This could mean being in another part of the house or another part of the city. It’s cool, and some people really like being able to operate their circulator from their smart phone. But don't forget about the pathogen issue: you can’t really leave food sitting in room temperature water all day--risky even if you start with frozen food--then turn on the sous vide 2 hours before you get home from work.
Connectivity is the wave of the future, though. Once again, the Joule wasn't on the market when this article was first published. The Joule is operated completely by a remote application from your cell phone (or smart home device like Alexa) and has all sorts of online recipes and easy-to-follow instructions. It's a different model than the Anova, and the result is a great product with all kinds of potential applications.
Attachment Design (Immersion Circulators Only)
Sure, you want one with a durable design, but it goes further than that. What type of vessels will you be using? What if you want to do a pork butt or turkey, and you want to use a large vessel such as a cooler--is the clamp or clip wide enough to fit over walls that thick? And how high does the water level need to be in order for the circulator to work? Because if you want to sous vide something in small jars (such as creme brulee, yogurt, or cheesecake), you may want a model that will allow the unit to submerge in fairly low levels of water (although you can also solve this problem with a rack, but that requires more infrastructure).
Overall, a clamp is the most versatile design. It tends to allow for the widest range of vessels. The Joule (see the review here) has both a small clip and a magnetic bottom. If you're not using a magnetic vessel, the small clip is a distinct disadvantage, and the only serious drawback of Joule's design.
Review: Anova Precision Cooker
Update (July, 2018): The Anova is now owned by Electrolux and since this purchase, the quality has gone significantly downhill. We now prefer the Joule instead.
Anova is one of the oldest sous vide manufacturers, and the Anova Precision Cooker is probably the most recognized brand of sous vide circulator out there. The Anova Precision Cooker circulator is economical, has a nice design, and does its job really well. It also has Internet connectivity, which no doubt will be available on all sous vide machines in years to come. The Anova has more than 1,000 reviews on Amazon with a 4.5 star rating. According to Fakespot.com, these are trustworthy reviews.
Usability and Design
First off, the Anova has a nice heft and a solid, expensive feel. Its stainless steel shaft and black case look really nice and have a minimalist vibe that makes you think it’s going to be delightfully easy to use.
Which it is. The Anova comes on when you plug it in, so all you have to do is set your desired temp with the scroll wheel and press the On key (the red arrow that looks like a Play button). The display is bright, big, angled, and easy to read. It shows both the water temp and the set temp, which is great (not all circulators do).
It beeps to let you know when it reaches the set point, and it beeps if something’s wrong. For example, if the water level is too low, it beeps and stops circulating: you have to adjust the water level and restart it to stop the alarm.
The beeps are different and loud enough to let you know, even if you’re in another room, whether it’s running smoothly or needs attention.
You can use almost any pot size with the Anova. It has an adjustable clamp so you can move the circulator vertically to adjust height for different pot depths. This is a great feature that isn’t possible with clip-on circulators.
The adjustable height feature also makes it possible to change the circulation direction. With the height screw loosened for adjusting, simply rotate the shaft to the position you want.
Speed and Reliability
At 900W (WiFi model)/800W (Bluetooth model), the Anova is not the most powerful circulator out there. It takes about half an hour to reach 135F from room temperature water. Using hot tap water will speed up this process, so I don’t find it to be a deal breaker.
Its reliability is good. The Anova guarantees that the circulator will keep a constant water temp within a hundredth of a degree (0.01F/C).
Independent tests have proven this to be true, even after several hours of operation.
Cleaning and Storage
The stainless steel housing is removable and dishwasher safe, so cleaning is easy. This is important because sometimes, bags break, and food gunk can get sucked inside the circulator. Of course, running a circulator in clean water for an extended period would most likely clean it pretty thoroughly, but the removable option is nice.
Because the Anova is small and lightweight (see specs below), it’s easy to store. It’s small enough to fit in a drawer or on its side in a cupboard or on a pantry shelf.
You can get the Anova with WiFi, or with just Bluetooth. These options allow you to set and control the unit remotely. You can remotely:
- Set/change temp and timer
- Delay start time
- Monitor temperature
- Access thousands of recipes
- Get notifications if there are problems.
As the connectivity is frequently updated, these options will change--but this is the gist of what you’ll get.
Will you use the WiFi and/or Bluetooth? If you can solve the Danger Zone issue (i.e., that you can’t leave food out for more than 4 hours between 40F - 130F without risk of spoilage), then you may love having the ability to start dinner cooking from work so it’s ready when you get home. One way people do this is to fill a vessel with ice before they leave for work and turn on the circulator in the afternoon to have food ready when they get home.
Or, you may want to monitor a long cook while you’re out and about. And it would certainly be nice to know if there are any power outages (for example) that may affect food safety.
Update (July 2018): We've not tested the newer versions of the Anova, since they were bought by Electrolux. But there are numerous complaints about connectivity issues, from not working with certain routers to being forced to log in to the app even if you're not going online for any reason. If you want Internet connectivity, spend a little more and get the Joule instead.

Review: Sansaire Immersion Circulator
The Sansaire Immersion Circulator has an interesting story. It was funded by a Kickstarter campaign which set a record for the most-funded food project, raising more than $800,000 in just 30 days. The product now has hundreds of reviews on Amazon with an average rating of 4 stars. Fakespot assures us that these are trustworthy reviews.
Like the Anova, the Sansaire is accurate, reliable, and powerful. We like it a lot. But it's a little bigger than the Anova, and even though it's well made, its plastic housing isn't our first design choice.
Usability and Design
The Sansaire has a sort of hourglass design that makes it look like a big peppermill. This makes it easy to grasp. It’s also flat on the bottom, which is a nice feature because you it means you have the option of storing it upright--not something that most circulators offer. It’s sleek black color and symmetrical shape make it great looking, but its all-plastic housing gives it a bit of a delicate feel.
The Sansaire is about half an inch bigger in diameter than the Anova, it’s a little bit taller, and at 4 pounds, it weighs almost twice as much. Thus, it will require a larger storage space than other circulators on our list.
The interface is simple, with just a power button, a Fahrenheit/Celsius selection, and a temp button that will display the current set point when pressed. The entire top of the unit is a rotating dial that sets the unit. It’s easy to use and has increments of 0.1 degrees, which is very sensitive. It scrolls quickly, so you have to get a feel for using it.
The actual display is on the side of the unit (see the video below). This is a little weird--you have to kind of be watching two spots at once to set the unit--but it was nice to be able to see the readout from across the room, which the side display makes possible.
The Sansaire attaches to a cooking vessel with a large metal clip. This clip has an adjustable width and is large enough to work on almost any sized pot.
Water level is where the Sansaire really shines. It can run with a water level between 2.75 inches and 6.5 inches, which gives it a total depth range of 3.75 inches, more than most other circulators on the market. This may not sound important, but if you’re doing a cook of more than 12 hours, evaporation DOES become a concern. So it's nice to know that it has a large depth range.
The Sansaire Sous Vide Immersion Circulator does not have a timer.
Here's an excellent, detailed analysis of how the Sansaire works:
Speed and Reliability
At 1100W, the Sansaire has a lot of power, more than all the other circulators we review here. It will go to 140F from room temperature in less than 20 minutes.
The Sansaire has been tested by many independent reviewers, and it has consistently proven to be an accurate sous vide machine, even with cooks of 72 hours.
Cleaning and Storage
The housing is removable for easy cleaning.
The Sansaire is a little bulky and heavy, but it will still fit in most drawers. And as mentioned earlier, its flat bottom makes it possible to store it upright, which is a nice feature.
The Sansaire currently has no Internet capabilities.
Weight: 4 lbs / 1.8 kg
Dimensions: 3.3in x 3.33.3in x 15 in / 10 x 10 x 38 cm
Voltage: 110V 60Hz US – 220/240V Euro – Aus/NZ
Power 1100 Watts
Temp. Range: 32°F – 212°F / 0°C – 100°C
Temp. Stability: ± 0.1 degree at 140°F / 60°C
Circulation: 3 gal / 11 L per minute
Bath Size: 22 gal / 83 L @ 67°C || 6 gal / 23 L @ 90°C
Low water level protection (auto shutoff).
Pros and Cons
Pros: The Sansaire Sous Vide Immersion Circulator has a minimalist design and a powerful motor, is accurate, reliable, and has an excellent water level range.
Cons: Plastic housing, no timer, no Internet connectivity, and a little bulkier than some other circulators.
If you want something more powerful (i.e., faster) than the Anova and you don't care about Internet connectivity, the Sansaire is a good choice.

Review (Best Bargain): Gourmia GSV-115 Circulator
We like Gourmia, a company known for producing reliable kitchen products at an economy price. (See our review of the Gourmia induction burner in this article.) The Gourmia GSV-115 sous vide circulator is a good bargain choice. This is a new model as of early 2019, lower powered yet at an unbeatable price.
It has an excellent interface, with a big, bright LED display, angled for easy viewing. It's designed very much like a slightly more streamlined Anova--probably exactly what they were going for.
It does not have any Internet connectivity, but otherwise it's almost identical to the Anova for about half the price. It comes with a nice recipe book to help get you started with sous vide.
- Angled face with white LED display
- Touch sensor controls
- Digital timer
- +/- 0.001 degree accuracy
- 72 hour continuous run time/auto shutoff
- Streamlined design
- 360 degree pump
- ETL certified
- Recipe book included.
The interface is pretty straightforward, as you can see here:
As you can see, there is no dial, so you have to change the setting by pressing the Plus/Minus keys on either side of the display. We prefer a dial as it's easier to use, but these touchpad controls are surprisingly quick.
The big timer display is also very convenient if you're using the timer.
We'd also like to mention the durable screw-on attachment:
You might think this is clunky and harder to use than a clip, which is true--BUT it's extremely durable and versatile and really preferable to a clip. This is going to fit more vessels, and it's going to last longer. Win win.
Weight: 3.05 lbs
Dimensions: 13.5 x 4 in.
Voltage: 110V 60Hz
Power 800 Watts
Temp. Range: 74F – 194F
Accuracy: +/- 0.001 F
Circulation: 1.5 gal/minute, multi-directional (360 degree)
Bath Size: Max 5 gal
1 year limited manufacturer warranty.
Pros and Cons
- Great price
- Comes with recipe book.
- Smaller temperature range than other circulators (only goes up to 194F)
- No Internet connectivity.
If you want to get into sous vide for the lowest price possible, this is the circulator to get.
The Gourmia is roughly the same size and shape of the Anova, and with 800W of power, will operate much the same as the Anova. (In fact, this is probably what Gourmia was going for with this design.)

Review (High End): Polyscience CHEF Immersion Circulator
Long before anyone thought of cooking food in a water bath, immersion circulators were used in laboratories to keep chemical compounds--from blood to salt water and everything in between--at exact temperatures. Precision is the name of the game here, as a few tenths of a degree in either direction might throw off the results of an important test. PolyScience has been a trusted name in laboratory equipment for decades, and only recently (probably the last 10 years) have they expanded into kitchen products.
Why would you buy a high-end circulator for hundreds more than you’d pay for an Anova or Sansaire, which do their jobs quite well? Here are a few reasons:
- Heavy duty use
- More powerful (i.e., faster temp control)
- Laboratory-level temperature precision
- Aesthetics you can love
- Made in USA instead of China
- You're a kitchen geek
- You can afford the best.
We’re not going to tell you that you need a commercial grade circulator. The only practical reason to buy one is because you’ll be giving it heavy-duty use and you need something that will stand up under these conditions. But if you can afford it, you may want to at least consider this route, because, well, because you can. And because it’s fun to have the best sous vide product on the market.
We only review one model: the PolyScience Chef Series. There are others in the same class and price range, but this one checks all the boxes and rings all the bells. If you're going to spend the money, this is the one to get.
Update (July 2018): PolyScience culinary is now managed (owned?) by Breville, a company mostly known for its toaster ovens and coffee makers. Some people believe the quality has suffered. While it's too early to say for sure, the PolyScience culinary products may not be as top-end as they once were.
Polyscience--see more of their ridiculously geeky kitchen instruments here--makes two kitchen model circulators: the Creative and the Chef. The Creative is a few hundred dollars less expensive (though still more than an Anova), but if your interest is a high-end circulator, the Chef is worth the extra money. According to their website, it is the immersion circulator that “sets the standard for sous vide cooking.” We have no doubt this is true, since PolyScience has been making immersion circulators long before they were used in the kitchen. It is the choice of professional chefs the world over.
Usability and Design
The PolyScience Chef circulator isn’t as pretty as some other units because it has a very boxy, industrial design. Its interface is even a little clunky, with Up/Down Arrows that change the temp. It offers no extras like Internet connectivity or a timer, and its minimum immersion depth is almost 3.4 inches, so it requires more water to run than all of the cheaper models we reviewed.
This PolyScience Chef Immersion Circulator is a tank. It is designed for commercial use and you can tell the instant you pick it up. It weighs almost 10 pounds--more than twice as much as the Sansaire and four times as much as the Anova. Yet it’s also fairly compact--roughly the same size as the Anova, but with a different shape--which makes it easy to use and store. It has a sturdy polycarbonate and steel housing that encases the entire unit and protects its inner workings from all types of damage. There’s even a cover over the water intake vent that discourages food particles from getting inside. Both the pump and the heating core are made of high grade stainless steel (probably why it weighs so much).
The display is huge and backlit, which makes for easy reading. It is settable in tenths of degrees and accurate to +/-0.1F (+/-0.07C). It has a powerful pump with a flow adjustment switch--this means you can have the power when you need it, and also conserve energy in small containers that don't need a powerful water flow.
The PolyScience Chef Series attaches to a cooking vessel with a screw clamp that looks like it came off an engine. This thing will never break or fail to hold the circulator exactly where you put it. It’s big enough to clamp to just about any container. However, it is not height adjustable.
Speed and Reliability
At 1100W, the PolyScience has a lot of power. While this is equivalent to the Sansaire, its stronger pump increases the rate at which it will bring water up to temperature. It has the fastest up-to-temp time on the market. Interestingly, this spec was hard to find, maybe because PolyScience takes into consideration many factors, including the water level, the ambient air temp, and how much food you’re trying to heat. In other words, it’s not as simple as “0-60 in 3.2 seconds.” But whatever you’re trying to do with it, you won’t find an immersion circulator (at least at this price point or below) that’s faster.
Its accuracy is also undisputed, and within 0.1F as stated above. One really neat feature is that you can calibrate the PolyScience Chef like a piece of lab equipment. You never have to worry about inaccurate temperatures again.
Cleaning and Storage
The housing is not removable. However, it encases the unit so thoroughly that internal cleaning shouldn’t be necessary. While you may be in an unfortunate situation where small particles of gunk get inside the unit, a good flushing in a clean water bath should take care of it.
Storage is easy with this compact unit. You can store it on its side, in a drawer or cupboard, or upright on a pantry shelf--yes, its flat bottom makes it possible to store it upright and save valuable cupboard or pantry space.

Sous Vide Water Ovens
Unlike the immersion circulators, most sous vide water baths don’t have a pump. Rather, they have an insulated bath with a sensitive temperature controller that keeps the water at a constant temperature. They run in capacity between about 2 and about 3 gallons. This is quite a bit smaller than the 5-8 gallon capacities of the immersion circulators. However, you can still fit several bags of food in this amount of water (from 12-20 four ounce portions of food), so the size limitation is unlikely to be a problem for a home cook unless you’re doing a lot of entertaining.
One drawback of not having a circulator is that it will always take longer for the temperature in the bath to equilibrate. This means you’ll have more hot and cold spots for longer times than you would with a circulator. For that reason, we at Rational Kitchen prefer the immersion circulators. But there are certainly good reasons why people would go with a water oven.
Why would anyone prefer a water bath to a free-agent immersion circulator? Here are a few reasons:
- It's more energy efficient (no pump, insulated, cover)
- Very quiet
- Can run one for days without having to add water, so great if you do a lot of long cooks (and you will be doing long cooks!)
- Like the looks of it
- Less steam in the kitchen
- Easy to use
- Have room for it on your counter, or storage space
- Prefer the ease of not having to set up the immersion circulator every time you want to sous vide.
These ovens are actually attractive, or at least impressive looking. So if you have the counter space and want to commit wholly to the sous vide revolution, then a water bath might be the best choice for you.
Review: SousVide Supreme Water Ovens
Sous Vide Supreme has been around for awhile and makes one of the best sous vide water ovens currently on the market. They have three options: the Professional, the Supreme, and the Demi. The three together have a few hundred reviews with an average rating of about 4.5 stars. Fakespot says these reviews are trustworthy and gives all three products an A rating. Check them out on Amazon here:
The Professional and the Supreme are the same size--3 gallon capacity, or up to 24 6 oz. portions of food--and similar in appearance, but the Professional is certified for commercial use (30,000 cycles), and you can find it in restaurant kitchens the world over. The Supreme is certified for home use (6,000 cycles). The Supreme comes with recipes and an instructional DVD, while the Professional does not. These models are “about the size of a bread maker” and weigh about 13 lbs.
The Demi is a smaller version of the Supreme. At 2.3 gallons, it can still hold up to 12 4 oz. portions of food. It is also certified for home use up to 6,000 cycles. It is “about the size of a crock pot” and weighs a shade over 9 lbs.
Design and Usability
The design is simple: it’s basically a waterproof box with an LED control panel. All the units have handles on the sides that make it easy to fill, carry, and empty.
The usability couldn’t be simpler. You turn it on, set the temp, and pop the food in. The unit also has a timer option, which beeps when the time has elapsed but does not turn the unit off.
Cleaning: Cleaning is easy, as long as you empty it out when you're done and store it empty. Wipe it out with a mild soap and rinse thoroughly with water.
The control panel looks complicated but it’s really pretty simple to use. Here are the basic steps:
- Fill bath with water.
- Press the Power button.
- Press the Start button.
- Set the temp with the Left-Right arrow keys and press the Set Temp button to start.
- If desired, you can also set the timer: Press the Set Timer button to switch to timer mode and use the arrow keys to select desired time. (NOTE: The timer does not turn the unit off, it just alerts you that the cooking time has finished.)

Review (Best Bargain): The Gourmia GSV-550 Sous Vide Water Oven
If you want to go uber economical, you could do worse than the Gourmia water oven. It's a little smaller than the SousVide water ovens and comes with some nice extras like tongs and an oven rack.
Gourmia is well known as a producer of economical kitchen products with a reputation for decent quality. For these reasons, we recommend this water bath as a "best sous vide" buy if you want to dip your toe in the sous vide pool. It’s an excellent entry level choice.
Design and Usability
The Gourmia water bath looks like an oversized crockpot. It’s stainless and black with a nice symmetrical shape. Small handles on both sides and on the lid make it easy to fill, move, and empty. One kind of neat feature is that you can use the lid as a drip tray--so when you remove food pouches from the bath, you have somewhere to set them down--no scrambling around because you forgot to grab a plate. The lid is also clear, so you can see what’s going on in the water bath.
It has a nonstick bath that holds 9 quarts of water (2.25 gallons). With 520 watts of power, it has the same amount of power as the SousVide Demi--a surprising plus at this price point.
Cleaning is as simple as pouring out the water and wiping the nonstick surface with a soft cloth. If descaling is required, use a vinegar solution at 100F for an hour.
The Gourmia is one of the best sous vide machines as far as ease of use. In fact, it is nearly self-explanatory, with these buttons: On/Off, Temp/Timer, Plus/Minus, F/C, and Start/Stop. Do you even need a manual with controls this straightforward?
When you turn the unit on, the default temp is 140F and the default time is 4 hours (as shown in the image here). Since these are commonly used sous vide settings, this is a clever shortcut.
The oven beeps when it reaches temperature and again when the time has elapsed. When the time is elapsed, the unit turns itself off. (Note: This may not be an appealing feature. Food, meat in particular, can sit at temperature in a sous vide bath for hours without ill effect, which is part of the magic of sous vide cooking. If the unit turns itself off while you're not around, the temp could cool down to the danger zone and your food could be a pathogen risk.)
The panel displays the temperature of the bath in real time, changing as the temp changes.
