"Great biner, great buy" - Review of Black Diamond Quicksilver Screwgate Carabiner

I like these Black Diamond lockers. They provide the security of a locker but at a low price. I use these for most of my locker needs. The one big downfall to these is the nose sometime catches on slings, gear, etc. If you can spare the extra money seriously consider the Positron or another locker with a keylock nose. I have been happy with my Quicksilver lockers and won't be replacing them anytime soon.
