I like the velcro on this band. Not mentioned is the strap itself is adjustable by easily sliding it, and it holds. As it is new I have not had the issue of the velcro catching as other reviewers mentioned. Adjusting the strap length allows all of the velcro to be covered.
I have very small wrists and like not having a buckle in an awkward place. I also like the option of easily fastening it to a purse strap such as airport security.
