With a screwdriver
Fitbit's Charge 4 trackers have convenient replaceable/interchangeable straps. Unfortunately the brackets/clips/holders that the strap clips onto are made of cheap plastic and are prone to failure resulting in potential loss of the watch or some pieces of the clip. If you are lucky enough not to lose the watch but need to replace the clip this is the auction for you. With the clip broken a perfectly good Fitbit is essentially unusable so rather that throwing out the Fitbit (and contributing to global electronic waste) use these parts to repair your Fitbit.
Warning
Parts are very small and easy to lose so please be careful especially with the spring and screws. You will need the appropriate small screwdriver (T2 Torx - supplied) to fit the tiny screws. Buyer is responsible for ensuring these are the parts they need, that the Fitbit case is undamaged and can accept the parts and is responsible for being able to install the parts. You will only receive the parts in
