Quality is second to none!
So far these bands are the best I've ever owned. I've bought several different sets of bands over the years and all of them have snapped after just months of use (full disclosure — I'm hard on my bands because I use them to replace heavy machine-based exercises usually performed in a gym). So far, while I've only been using them for a few weeks, these clench bands seem like they might be the last bands I ever need to buy. They aren't showing any signs of wear and tear despite my heavy use, and their unique construction suggests they won't succumb to the usual minor nicks and scrapes that ultimately lead to the destruction of cheaper bands. Well worth the money!
