I do and love it!
(But I'd likely get Go Wear Fit if I were a new user: more info and less $).
We are poor too but I go it before Overtime dried up and I had been doing WW online but changed to BB and while the device is $$, the site subscription is less $ than WW). Plus I find calorie counting easier as the #'s are what they are.
Oh and my brother and his wife purchased the digital display for me around my halfway point to help me keep going. That was so kind, I am lucky!
