Metolius  Steel Auto Lock Carabiner

I purchased this biner to attach my LRS device to my harness. The Petzle Tangas fit well to hold my gear in place as well. I plan to order another one to use as a TR anchor for long days at the crag with beginner climbers. It's a well made product. The spring is only slightly stronger that my other Petzle & DMM auto lockers. Minor axis strength is 15 kN btw.

Works great! Very strong spring for the auto locking system. Only thing is that the advertisement shows a dark gray as the color when in reality it’s more of a true silver.

This is a 40kn, positive locking carabiner I use as a main anchor for hauling up. If you can find anchor spot, it is strong enough, I use it to hoist elk.

The Metolius Steel Auto Lock Carabiner is an awesome device which is very well made and beautifully constructed. I failed to properly read the description so I missed noticing its weight and size, it wasn't right for the application I had in mind so I passed it along to an adventuring relative who didn't mind the size and weight.

Extremely strong and durable. Haven't had any issues. Feels weighty in hand.

I'm giving this carabiner 3 stars not because it's ineffective, but because the design is not the best. The spring on the clasp is VERY strong, which is good for safety, but is a pain to pull down and twist to get belay devices etc. through it. If you're rope climbing in a gym and need to take it on/off and all it is very difficult to open especially when your tired from climbing

Very heavy. Feels about double the weight of my big D it was supposed to replace. Same general size, same locking style, double the weight. It will work but it's unrefined - lacking the nuanced shape of other big Ds, hard somewhat sharp edges on the turning mechanism, a tight spring that wasn't quite meant for this purpose. And did I mention, heavy!!
