I have been using the Anova Sous-vide stick for about a month. The unit does not work correctly, the temperature randomly resets. The timer is just junk. Setting it manually is next to impossible, so I use the App on phone. I don’t know why it just randomly goes from 129 to 61.1, I mean 61.1? WTF. I would NOT recommend this thing to anyone. Anova shame on you for making such a trashy product.
UPDATE: I have determined the Issue to be with the Anova App on my phone. I stopped using it and have experienced much better results. I just set the temperature and let it go however long it needs. Much better.
