I bought a couple of these babies to use for multi-pitch sport routes. My only complaint would be they are on the small side for a locker. But unless you need to stuff a giant rope in it, it should be able to handle almost everything you'd want. I love using it as a belay biner with a 9.6mm or smaller rope. If you're looking for a Locker to slip into the power point of your 1" webbing anchor, I'd suggest something bigger. But for almost any other application, these little beauties perform like a charm. And you get a locker at the weight of many of the non-lockers on the market. They're tough to beat in my opinion.
