OK. Might Want to Consider a Different Brand
on March 2, 2018
Overall, the reviews of this product seem very positive; however, I am disappointed. I was especially influenced by the reviewer that said this circulator heated 2 gallons of water to temperature in 15 minutes. That is not true with the unit I received. The statement “to temperature“ is deceiving. The question is “what temperature?” I added exactly 2 gallons of distilled water to a large pot with the water level approximately 1/2 inch below the max fill line. The initial water temperature was 66°F. It took 48 minutes to heat the water to 140°F. After letting the temperature stabilize for 10 minutes, I measured the temperature with three different precision thermometers (accurate to ±0.7°F). Each indicated that the temperature was actually 143°F. I checked the water temperature every 10 minutes for the next three hours and the unit did maintain 143°F without varying more than 1°F. Also, that review were stated that the unit was a 1200 W unit. The unit that I received states that it is 1000 W. It is displayed prominently on the outside of the box.
If you have a precision thermometer to monitor the water temperature then this unit is certainly usable. It does seem to maintain temperature, but it is not as accurate as I expected. Many of the sous vide units advertise an accuracy of ±0.1°F.
UPDATE: I failed to mention that when I measured the power usage of this device it only registered 800 W (that could explain the long time needed to reach final temperature). However, a friend also ordered one of these units and he was kind enough to loan it to me for testing. I tested it and the power draw was slightly over 1000 W which would agree with the markings on the outside of the box. It also heated water much faster than mine. It only took 32 minutes to heat two gallons of water (starting at 66°F) to 140°F.
I still stand by my initial conclusion. You are probably better off considering a different brand. Given the different heating capabilities of the two units, I am a little worried about quality control. However, if you are willing to monitor the output temperature to determine that it is accurate, then this unit is certainly usable. So far, I have been able to successfully cook several dishes using this unit. I still stand by my initial rating, this unit only deserves two stars.
