Bought Ron a clip-on FITBIT and he prompty lost it so I went out and replaced it with a wrist "Flex" and I added one for me to the credit card. Mine got five days of LESS THAN aerobitic heart pumping activity and then I conveniently, and probably with malice; left the charger in Duluth, I am awaiting the UPS truck. UPS just "Dropped " it at the door.
I would rather insert bamboo shoots under my fingernails than exercise. It cost me $55.00 to ship it back so I am quite literally invested in this piece of technology which actually told me I wasn't sleeping in the first five days. After printing a 27 page "User's Manual" I discovered when you go to bed you have "talk to the FITBIT telling it "I am going to sleep!"
