Bought these for my wife. Your rubber band that comes with the Fitbit caused a severe rash/reaction. Apparently this is a fairly common problem. Until now, these things have been the cure! You can't beat the price. Especially when you consider that even if they don't last as long as a standard strap, many of them have to go through before needing to be reordered! They are cool! She has zero complaints.
