Exactly what I wanted at the price i wanted
Stopped working within a month. Fitbit sent me a new watch then charger broke.
Turns out it was used and I did not know it. Went to go get the 6 month premium trial turns out it was already used by the previous owner. Thought the price was on sale turns out I was wrong.
The product came completely dead and it won't charge
I like the Fitbit sense watch but the charger does not charge the device. You can plainly see one of the pins on the charger does not stick out as far as the other 3. Now my battery will be dead before I can get another charger.
