text: The features are nice, when they work, which is infrequently. The Bluetooth range is short, which is fine. we all know what we're getting into with the Bluetooth game. My issue is the device will fail silently and get 'stuck' on a temperature and gives the user absolutely no indication that anything has gone wrong. I have tried it 3x for smoking meat and it has failed in this way about 10 times. each time the only way i can figure it out is to notice that the temp stays the same for a long time, like 20 minutes or so, and then I must power cycle the device and force close and reopen the app. After i do this it starts working again. Unreliable garbage.
