So far, I'm definitely enjoying my experience with it. I'm obsessed with how many steps I take a day, and how I can walk just a bit more to increase my number. Today, I wanted to reach 20,000 steps so I walked a friend home just for the sake of it (Unusual on my behalf!)
The stat that I like to look at the most is my active moments. It shows how many steps I've taken and when.
The other night, when I didn't quite remember walking home (don't ask), my trusty Fitbit remembered for me. So, I guess I'll never be quite alone!
