I've never had one of these straps break yet but I wanted a collection of all different sizes for more mounting options. I was surprised to find that I could also use these straps on other knog lights. I ordered one of each size and one of the bags labeled Large had a Small in it, but after contacting support they offered to send out the proper one. Since they are only 70cents each I said that it wasn't necessary. The support was friendly and helpful and has even agreed to send me longer bolts for the Knog Scout at no charge. I'm very pleased with my Knog products and will be ordering more.
