I purchased these as a Plan B for exercise while traveling, for my off days from yoga, and a nice outdoor stretch/workout on the weekends. I've only used it a couple times, but it seems really sturdy and haven't had any issues. The door anchor works great too! My only complaint is the straps do rub on your arms when doing certain resistance exercises. For example, while standing on the band and doing bicep curls, the straps rub on the forearms, but It's not too terrible.
