Didn't last

I used this ankle strap a total of three times for leg extensions on the cable machine, and the velcro is already done. The first time worked like a charm, the second the velcro kept letting go mid-extension, but I was able to make it through, taking extra caution to be oh so gentle, and the third time I couldn't even do one extension without it coming undone and slamming the weights down on the cable machine. Very disappointed, especially after reading the good reviews of others...
