I usually buy another brand from Revain to replace my straps. I don't think I can mention the name in the review but they are in the top three for about ten bucks and the reviews are in the thousands. It's ok, but the ones I usually buy are of much better quality. They're bulkier and difficult to stuff into the loop once you've put them on (if that makes any sense). It doesn't slide smoothly into the device, I have to wiggle it before it actually snaps into place, in one of them I have to physically adjust the piece of metal to make it snap into place. They sit tighter on my wrist, which leads me to believe there aren't separate small and large sizes. They will end up pairing well, I basically bought the set I got because I wanted deep purple and teal and this was the best deal to get both colors I wanted.
