I just received this in the mail and it was very easy to setup. I was surprised with how easy it is to read also. Fits like a charm as long as you print off the fit guide from Nike's website for it. The mobile app for the FuelBand is also just OK. Not great but not bad. It's easy to sync with the FuelBand but it would be nice to see distance walked/run for the day in the mobile app like you can on the web.
I can get about 36 hours out of the battery. And that's with syncing it to the mobile app and checking time on it. Never tested the battery when I just let it go.
I would recommend this product to an active person who likes to keep track of there activity. I have found it pushes me to be more active and pushes me to reach my personal goals I setup for myself.
