I love that it auto synchs and has a backlight. The battery lasts a year or more, and it is waterproof! The fact that The 2 would sometimes reset instead of synch, losing all my data.
Bought this for my 15 year old cross country running son. He likes it but noticed the band quality is not the best. Rubber is starting to peal away from tracking unit in less then 8 mo of wear.
I love the colors in this pack. Four colors that can go with any and every thing I wear that is very nice. These fit well. I would recommend these rings to any one who would like a variety to choose from and not want to worry about damaging a traditional ring.
