I ordered 3 packs (150 staples) and have used 2 of them so far. Of the 100 used, 6 were either damaged upon delivery (hook broken, no rings to attach) or broken during use (mostly on the hook). I use them to make name tag straps so they don't appear to have a lot of weight or stress hanging off them. The material is thin and can break during assembly. They're good for the money, but 6% new parts breakdown seems a bit much to me. I'll still buy and use them, but I'll have to factor the level of breakage into my cost. YMMV.
