Rated 5 out of 5 by Bryan from 5 years in and still going strong I am a professional chef and bought this machine as my first go with sous vide cooking. I have owned it now for more than 5 years and the little thing is still going strong! I have used it to cook pork ribs (48-72 hours), chicken breast, steaks, seafood, veggies, eggs, you name it, it has really changed how I cook. I am sad to see the negative reviews here with machines failing, but I have had the opposite experience. I have pretty well abused it and it still works like new. I would highly recommend this unit.

Rated 3 out of 5 by Weinstein from Poorly manufactured I bought this product at SW. After a month of use the electrical cord started to short out and it stopped working. Replaced by SW. After another few weeks of use, the case started to warp and the seams opened. This time I contacted PolyScience and after sending them photos of the warping case and a purchase receipt, they accepted it back and sent me a replacement which has been performing well for the past six months. If you look at customer reviews on Amazon you will find that many purchasers have had similar mechanical failures with this machine. Seems that manufacturing and quality control are very poor with PolyScience.

Rated 1 out of 5 by CarlN from Not built to last We used this device for a few months, and liked it so much we purchased a second one for use on our boat. Unfortunately, the second one started smoking 9 months after we bought it. Fortunately, it blew a breaker and shut off. This unit is not designed to be used for more than 12 hours at a time.This is unfortunate, because some recipes require sous vide cooking at up to 72 hours. So, if you want to make a nice Osso Bucco that cooks for 72 hours, this is not the machine for you. At this price point, it doesn't make much sense to buy this if it only lasts 9 months. You can get immersion cookers that cost under $200, which are more like a disposable unit.

Rated 2 out of 5 by steve415 from Worked for a year and a half, then burned out I have mixed feelings on this one. It has served me well for a while, but failed yesterday. It shorted and burned up inside the control unit, melting the case, and now it no longer heats up. (Photo of the insides attached.) Looking online, it sounds like a few other people had this problem, so I think I'll replace it with a different brand.

Rated 5 out of 5 by Stefano from One of my favorite toys When I first started experimenting with sous-vide, I envisioned a device like this, and I was very happy to find out that it existed and was reasonably priced. I love the fact that you can just clamp it on to whatever container is appropriate for what you are doing. It's easy to use, straightforward, it's an elegant design, and the accompanying documentation is clear and concise. It gets the water to temperature very quickly also My only nit is, as I think another reviewer mentioned, it would be nice if it somehow retained the previous temperature setting so you don't have to take the time to set the temperature each time you use it.

Rated 5 out of 5 by girl1der1975 from My husband's new favorite toy I bought this for my husband for his birthday and he absolutely loves it. It is easy to use, easy to clean and stores easily. I also bought him the Modernist Cuisine book which has many recipes that use sous vide. This was quite helpful in knowing what is possible with a machine like this.
