Excellent, better than original charger,
Verified Purchase(What is this?)
This review is from: VicTsing Replacement USB Charging Charger Cable Cord for Fitbit Flex Band Wireless Activity Bracelet Charge - 0.59 feet Black (Personal Computers)
Got this as a replacement charger for the one I left in Istanbul. First of all, prime service means that I got this package before my fitbit ran out of battery life... #FTW.
The flex clasps more securely on this charger, and there are no compatibility issues. It does what it says on the tin.
Would recommend it to others.
