I rated this monitor 1 star at first because the first one they sent me didn't work. The support team contacted me immediately and sent me another one and it arrived even earlier than they advertised. The second works great and is very convenient. I use a punching bag to exercise and needed something that could measure my stats somewhere other than my wrist as these devices can't withstand the effects of boxing. It helped and has good coverage. I haven't tried the save function yet. I'm taking off a star because it's hard to know when to charge the device and the instructions aren't very informative. Connect the device from the Bluetooth settings and then from the monitoring app. I use FITIVPlus and it works great.
