Bests & Worsts Reviews from Amazon

Ordered the ring and downloaded the android app (in beta, but works fine). I received the ring sizing kit in the mail and then finished my order with my selected ring size. The ring is surprisingly lightweight which is great cause I really didn't want a heavy or bulky bit of "jewerly" (reason I didn't want a watch or bracelet). Once you take the ring out of the package you have to pair it with the app - this was really simple and easy. I just plugged the USB adapter (I used my cell phone charger but you can plug into a laptop) and attached the ring (magnetic), and then opened the app. It finished pairing in about a minute. Charging the ring is pretty quick as well (charge is lasting about 3 days). I've slept, showered, sweated, and washed dishes with the ring on and haven't had any problems. Also, I don't have to keep the app running since the ring stores my data until I sync it, which is great because then my phone battery won't be drained by having another app running. I'm really enjoying this tracker, it's simple to use, pretty, and comfortable.
