A few issues, but great otherwise
I've had two serious issues with this carabiner. First, it seems to try to get cross-loaded more often than other 'biners. That lead me to abandon its use as my belay 'biner. Second, the screw action is too smooth. I know that sounds crazy, and it feels great, but it unscrews if you breathe on it. I worry about the rope spinning it open. Other than those two not insignificant issues, it's a really great locker. I like the light weight, the smooth nose, and the "red is dead" stripe under the locking collar. I just wish it wasn't so prone to cross-loading because it's really minimized my use of it, which sucks for such an expensive 'biner.
