I have tried several different replacement straps for my Fitbit but they are as close as possible to the original Fitbit bands! Same type of metal snap button closure, indicator holes closed - other versions I tried were just open holes for dirt/dust to get in. The material is rigid plastic while the cheap silicones were flexible and just annoyed me. I removed the loops that are supposed to hold the extra slack in the band, but if you choose the right size they are not needed at all. Will definitely buy more if needed :)
