Wanted to like it!

Saw this on Hard Is Easy's YouTube channel while in the market for a new belay carabiner. So, I got this for my wife and me. But both of the crosslock mechanisms stopped working within weeks. The crosslock just keeps sticking, up or down. I hadn't even put it through a season at the Red River Gorge where sand is the enemy, and both of the crosslocks were sticking and making it really difficult to easily open and lose it. I returned both. Sad, really. It's a really cool idea, and I hope Mammut keeps trying on this kind of idea. But I'm thankful I bought this at REI. They returned these with no problem. REI is AWESOME. Totally have my allegiance.

The crossloading gate jams up leaving your belay/rappel device unuseable. It sucks to be on a multipitch with your rappel device stuck to your rear harness loop. I ended up just using a carabiner rappel. At home I used a toothpick to release the spring, but it still jams after cleaning and lubing. This carabiner design should be recalled and the designer should be fired.

First Impression is solid, may be a little tricky to get used to, but it seems like with some practice it will be my go to for my belay device
