Love it!
While my wife was pissed that I spent $100+ for something that tells you how fat you are the fact that it syncs up to your fitbit account makes it awesome!  If you have a fitbit this is a must have accessory.  I have had mine about 6 months and it's still working great.  The battery is still showing full and I step on it roughly 5 days a week.  Not sure how often my wife steps on it but I am not going there.
