If you have a damaged strap on your surge, you have probably been told it can't be replaced. Well now it can.

This is a replacement strap

There are youtube instructional videos out there to show you how to do it. It works OK as is, I didn't use glue when I replaced mine. If you want a really secure fit you can also add a bit of plastic safe glue like ados or uhu. I don't include glue as technically it would make the package dangerous goods

This is my cheaper unbranded version. It does work fine. But I also have some branded ETOPER ones which I have trialled myself and are even better than the original fitbit strap.
