Review on 🖤 Mio Slice Heart-Rate Monitors, Stone: Small Size for Precise Fitness Tracking by Kyle Beaner

This is a very disappointing unit. When it works, I really like it. But when it doesn't (which happens all the time), I get very angry. The stated battery life is a joke. I literally have to charge mine every day. That's right - not every fifth day, but every day. So plan for it. Once a week it stops syncing with my phone. When this happens, I get disgusted by messages like "device not found" and "pairing error" for about an hour, the program says that the device is connected, but for some reason the first screen of the application knows something that the second and third screens. no I wish I could rate it higher because the concept is good. But wait for version 2 if you don't want to spend a lot of time messing around with the app.
