> 7 day battery life Been using the fitbit air since day 1 and it never died on me. Charge it when I shower. The only issue is the fabric strap is getting dirty, and the sensor gets a bit dirty (dead skin, etc.) compared to an Apple Watch.

Other than that, it's spectacular, and now with Apple Health, it's on par if not better than the Apple Watch. apple health only synced to the 4-5 of July, though. :/
