I've been using a FitBit since Christmas.
I got mixed reviews when I asked about the Fit Bit here for Christmas gifts. I bought the wrist one for myself and I love it. I have lost 7 lbs since Dec. I didn't change my diet much just being more active. I didn't realize how little activity I was getting. I thought it was much more then it was. Little thing like walking from parking lot the store, turn around and walk back to your car and back again. It really adds up. With health care cost soaring every step helps.
