Fitbit Charge bend retainer

I have had the band on my Fitbit Charge come loose more that once and a family member lost a Fitbit Flex do to the band coming loose.

This is a very simple band retainer that you place on the band, fasten the band as normal then slide this over the back clip. It's a snug fit (not to tight but enough to prevent slippage).

Note that I am not responsible for the use of this device, loss of device or any other damage. It's up to you to decide if it's workable.
