As a professional geek, I was extremely disappointed to find out that the Anova couldn't handle my strong Wi-Fi password. (No more than 18 characters and NO SPECIAL CHARACTERS.) I had purchased it at my local Best Buy and after working with tech support, ended up returning it. After a tip from a friend, I ended up buying the ChefSteps Joule and it's fantastic. It's more energy efficient, heats up water faster, is smaller and easier to pack up and throw in a drawer, has a magnetic bottom for sticking to the bottom of a metal pot (well, any with the requisite iron in its alloy), and the app is about a billion times better than the Anova's. If you want to control the Anova while away from home, you have to buy the more expensive Wi-Fi unit, and it requires a different version of the mobile app, which currently doesn't have developmental parity with the bluetooth version -- it's not as up-to-date, has less features, and crashes a lot. Trust someone who's had both -- the Anova is NOT the way to go on this one until they fix some problems.
