These are horrible. I bought a refurbished Charge here about a month ago to replace my old smaller FitBit. After a few weeks it couldn’t even make it through a day without needing recharging.
Don’t buy a Fitbit! My current Charge (replacement for a previously defective Charge) is falling apart after only a few months. Just like my previous tracker. Fitbit replaced a defective tracker with another defective tracker. Right now it is charging, which requires me to tape it together so the charger will make the connection with the tracker. Their products fall apart within months and are junk. Go with a different brand.
bought a fitbit charge was ok up until i went on a trip and left it home, when i returned it was dead - charged and now will only work for a day - before it went a week before needing a charge.
