Rated 5 out of 5 by from Smooth, Easy-to-Use, and Secure Locking Carabiner! This carabiner, unlike other types of locking carabiners, is much easier to use and gives the same, if not better, peace of mind when being used. I use it when belaying and it is a rock solid locking carabiner - easy to check the lock and easy to unlock, yet secure. I ordered several more of these to have in my gear stash because they are such a dream to use. They are smooth all the way around the inside, and nothing gets hung up, in contrast to the screw-lock and twist-lock/auto-lock rings of other locking carabiners, which provide ample opportunity for the rope to get hung up on and twisted. This carabiner is smooth, easy, and puts my mind at ease.

Rated 5 out of 5 by from Amazing Carabiner This carabiner is both easy to use and to check for safety. The pinch feature has just as much flow as your favorite route, all while removing any edges or locks for the rope to hang up on. Even if 1 of the 2 locking magnets isn't engaged there is no way to open the gate, which gives me an added feeling of security. Love it.

Rated 4 out of 5 by from Good Have used the vapor lock before, switched over to the rocklock because of higher working load.. smooth and easy to use.. if using on construction site, or anywhere with metal shavings from drilling, grinding, welding, etc. the gate can become clogged, difficult to clean and not lock

Rated 3 out of 5 by from Mixed Feelings At first I liked this beaner as it is nice to have the auto lock feature and it makes a reassuring noise when it locks. Its great for use in the gym and on single pitch sport routes. Unfortunately, it is not the most user friendly on multi pitch routes as it is easy to drop your ATC when unclipping using one hand. Also, the black paint on the beaner will rub off on your rope, causing your rope and hands to end up covered in black paint.

Rated 5 out of 5 by from Beautiful, simple, easy to use and secure Here's some thoughts; - Normal screw locking gates can get stuck - These don't - these are very light weight - these are BIG...but not too big. It's like the 3 bears story, eh. - One hand pinching, on and off. Super easy - I like the big opening to allow to several ropes and slings fit in. I don't do it often but when I need works now. - It is so clean and beautiful

Rated 5 out of 5 by from Sleek Looking Locker That's Easy to Use Not too much to say other than it works and looks cool. I much prefer the pinch unlock as opposed to twist, easier to grab off your gear loop when you need it. Everyone who has seen me using this has commented on how cool it looks, hah.
