Anova Sous Vide Precision Cooker Nano 3.0

This is a genuine piece of garbage. You have to use app to set and maintain temp and timer. App spontaneously disconnects without warning or alarm that it has disconnected, so unless you constantly monitor the app, it will shut off stopping the heating and circulation of the water bath without notification of a problem and you are left wondering how long your food was actually kept at the designated temp. Additionally, the set temp varies up and down by SEVERAL degrees when it is actually running. And, best of all, this was a gift, so by the time it was opened and used the return window had closed, by 9 days! Horrible, horrible, horrible. DO NOT BUY!!!!!!!! (BTW, I was forced to give this 1 star in order to submit the review - I would have preferred zero.)
