Solid, comfy, and light, but…

These things are super light, feel nice in the hand, and have a decent gate action. That said, I’ve found that the screw likes to lock closed after being loaded, even after something static like anchoring. I would unload it, then have to use two hands to break the screw loose to unlock it. Not ideal when trying to release from an anchor to rappel. I own like 5 of these, and experienced this on multiple of them, so not isolated to a possibly defective single carabiner. They still do their job and are light, so I’ll keep using them for the time being. I just won’t rely on them for situations where one-handed operation is required. Black Diamond and others should also be aware.

Nice size

The thing I appreciate most about this carabiner is how easy it is to use with one hand for those of us with slightly smaller hands. It is still big enough for a clove hitch and many other uses, but is still small enough to manipulate quickly and is quite lightweight.

Vapor lock

Outstanding locker. Lightweight, no frills pear shaped crab. Ideal for uses where the rope is not moving though well suited to those uses as well. A good option is to pair the heavier stock Rocklock with an ATC and use the Vaporlock to clove hitch the climber to the anchor. However you choose to use it this is a finely crafted carabiner.

Perfect multipurpose biner

This has replaced my other hms biners because it’s very light but still holds a munter or clove on my larger (10.4mm) ropes. Im not sure it would do a munter well with anything bigger than 11mm. It’s strong enough to use instead of D shaped for everything else and light enough to carry several, so i use these for the majority of my locker needs (bulletproofs are my other lockers for the high grit rope rub situations).

Great size for use at

Great size for use at anchors. Plenty of space to clove hitch and the screw gate is smooth.
