Unreliable connectivity
This device always seems to be disconnected to the app. The timer disappears every time you check the app to see how much time is remaining. It’s also not as effective as it’s marketed to be. Especially for Pain Control and Relaxation. It doesn’t even have a placebo effect as I want to believe it to work. Wasted money, which I would gladly be refunded for if not for the very limited window to get my money back.
