I bought a couple of these about a month ago and have been using them for belaying and to clip in. I'm very pleased with the design and size and shape. I have larger carabiners that I was using and though thier nice and all, theye're heavy compared to this guy, and because of the size of my other carabiners they would spin when I would I belay or climb. I didn't like it. With this carabiner it doesn't spin when I belay or climb. I love it! I will be buying more in the future.
