I got 6 of these biners to do everything from set up anchors and top ropes to belaying and rapelling. They worked well for all applications. My favorite part is that they never get snagged on the rope or webbing. One of them got scratched more than I would expect when I was climbing over the edge at the top of a cliff. I'm not sure if this is normal, and just showed up more because they are orange so the silver scratches showing through stands out more? I hope this doesn't affect the safety of these biners, maybe someone could tell me. What I was doing was nothing but normal use. PS.... THEY ARE REALLY LIGHT!!!
