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.

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.
