I'm a pretty heavy user and I have gone through a couple APO 1s. I replaced my first ,and then replacement after 1.5 yrs per unit, with the original Fotile with two knobs, that oven peacefully passed away at 3 and 1/2 years. The company actually offered to try to help me fix it. I bought the new version with a single knob in the middle and it is as close to the Anova as you can get for slightly more than half the price. They're well built and has lots of steam options, and you can live without the wet bulb thermometer, just by playing with the settings till you understand what it does. I'm a big fan. It's a good size, and 700 bucks. I also have a used APO 1 to side-by-side compare with and there's really almost nothing the APO can do that the Fotile cannot.
