Literally broke in less than 5 minutes
February 19, 2017
Broke first time I used it. Was using the Velcro foot cuff, the seam where the buckle is affixed to the foot cuff failed completely...lousy sewing job. Looks like only one run of thread in the seam...and the thread compromised almost immediately. Got very lucky no-one was hurt and no serious damage occurred when it snapped. The workmanship is nowhere close to what it needs to be in order to stand up the the resistance that can be generated using the bands.
Don't buy this, lousy quality.
