Input:
This band set seemed expensive compared to deals I have seen at the store. Once I got the package in the mail, however, I realized that this is a truly professional setup. They appear far more sturdy, complete with metal clips (I don't know the correct terminology for the fastener thingys). I was surprised at the amount of weight that they would resist with - not to mention the door anchor and ankle strap comes with them. Most certainly a good buy.
