Convenient and secure attachment to Fitbit+ flush with no gaps. I haven't had any problems with them. I have a 7 inch band and wear the small watch band that came with my Fitbit so I ordered the SMALL size of this band. The rivets snap firmly into place. I'm not worried about them opening. I can wear it with notches 3 and 2 on the end while I work out for a snug fit, or with notches 2 and 1 on the end to make it looser during the day and when I sleep. Due to the looser fit, the HR monitor still works. I can't wear it any tighter. At my 7 inch wrist size, I would say that both the small and large sizes would fit me with no issues, but I like the small size so there isn't a lot of overlap and volume on the bottom of my wrist. I will definitely be ordering more flowers soon!
