So, I've used it twice...once on the trail and once at the gym. So far...nice! It has the magnetic charger which is convenient and lites up when fully charged. The unit has a power button...a very positive feedback experience, compared to passive power ups like chest straps. I wore it on my upper forearm and it was able to track HR without issue. I paired it with polar beats and it tracked HR from start to end. Battery status shows in the app. At the gym,it had no problems even with arm movement. I Nordic walk a hiking trail and again, no comms issues. Once the device was in beats, it picked it right up. It comes with a second strap, so I can swap them out to clean them. It's small and I forget it's there after I'm into the workout. I especially dont miss having to set the strap like a chest strap. If it holds up, I'll keep coming back. Regardless, I'm sold on forearm strap formats over chest straps!
