S2 tracker - gem bracelet

I think it's really a good product for its price. You can check the status by syncing with Apple Health Care.

Item has already stopped working didn't last upto 3 weeks

Good, despite some minor disconnections.
Otherwise nice.

Okay, but for me, too little functionality. Tracking of sports activities only with maps, so only outdoor activities, in the fitness studio it only counts steps but not calories. Otherwise very beautiful, you can shorten the bracelet with the equipment that comes with it, charges quickly, battery lasts a long time.
