Had it for a week and it fell off while out at mall never felt it come undone or fall off... just was GONE when I looked down. Should have listened to other reviews that said they LOST theirs also. So take my advise if u buy this either DUCK TAPE it to your wrist or DON'T wear it at all cause if u do you will loose it and that folks is a FACT! Looked for hours for it never found it what a waste of $ . POOR design by Samsung and they do not even acknowledge their design engineering fault. In short STAY AWAY from this until Samsung redesigns band .
