It's all I could ask for in a sous vide widget. Quiet, precise, easy to set the temp, fast to heat up a couple of gallons, and it stands on the countertop by the stove when it is not in use. It's main competition seems to be from the Anova folks. I've heard lots of happy people talking about the Anova product's performance. I still prefer the Sansaire for its heat exchanger extensibility, and for its design where it doesn't need to lay down in a drawer or such for storage, it just stands there.
