"Favorite Biener on the rack!" 04/14/13

This is my go to when I belay, need a biener to daisy on to, or just want to hang my water bottle on something. The spring and arm work very well and does not show any signs of sticking a few months after heavy use. Lightweight, strong, and looks legit.

"Favorite Beaner on the Market" 02/26/13

I climb with this beaner at least 3 days a week and it has held up to all my expectations. The screwgate is fluid, sits well on the harness, and feels lighter than my other beaners. Love this thing. I want more.

"It does what it's intended to" 01/04/13

Though I use BD products usually I must say that the Mammut has much smoother action in the screwgate that the BD. It's sturdy as all carabiners should be and has smooth opening action as well. Don't really know what else to say about a carabiner. It's solid.

"If I had to do it over again, I would still buy it!" 11/27/12

I bought this to use with my Grigri 2 (because the blue screw gate matched the blue grigri perfectly! (although it doesn't really look like it in the picture)) I am very happy with it and would buy it again. The only down side is that the grigri doesn't really fit around the small side of it so I have to make sure it doesn't try to twist around or it gets a bit stuck. Other than that I love it.Andy

"not a great belay biner, good all-around HMS" 10/01/12

I used this as a belay biner for a while and was amazed how fast it started wearing ridges. The edges wear down really quickly when used for belaying. Wouldn't use this for anything that is going to have a lot of rope moving through it for very long. Converted it to a general purpose HMS and couldn't be happier.

"Great reliable quality built product" 08/23/12

Love everything about it. Use it to hang bear bags, hang hammocks, climbing and used it once to drag a car out of a ditch. Love it and has never failed me. Occasionally however it is difficult to unscrew it but if you work it a little it will release.

"My favorite HMS" 06/15/12

I've seen and used several different types of HMS biners, and this is definitely my favorite. The color is a little darker and less shiny than the picture, minor detail. I got the twistlock version and it feels great, it feels very solid but still very light. If anything, the only issue with it would be that be basket is kinda narrow, which may have trouble accommodating some wider belay loops or slings, but works just fine with the BD Momentum harness. It is easily opened with one hand and snaps back closed strongly and firmly, leaving no doubt it is solidly closed.

"Coolest design ever and works at an affordable price" 04/23/12

This is one of my favourite biner! It is very cool looking with Mammut's unique I-beam construction of the body. Very light weight and the twist lock is smooth working. Doesn't take too much of extra strength nor hassle to twist open the biner unlike some other auto locking biners. Big D fits most devices too! Yet another awesome product from Mammut! The other version the mythos was too small for some devices btw.

"Great Biner. Love the gate!" 01/07/12

Awesome screw lock that screws like Ron Jeremy himself. This thing is smooth and quite, yet feels solid as a rock. The gate has some good tension on it and is all around a classy looking device. It is 58 grams, but the only problem i can foresee (i don't have this issue due to the size of my gear loop "arcteryx a300a") is that the gear loop side is a bit small. Which could cause problems, when belaying a lighter person where there isn't as much tension on the device. This typically leads to the biner laying on its side and obviously in a much less safe situation. For a little more in depth review, check out the review on YT. /watch?v=IWR2C0V3vGw

"Looks GREAT, performs just as well." 10/24/11

My favorite locker by far. The screwgate is beautiful to use and you only ever need one finger. The tension on the gate is heavy enough to keep it from opening while you screw it shut, but light enough to make clipping in fairly easy. A little bigger than i expected, and i was glad to see that. Another well designed piece from Mammut that will look great in your rack (...and keep you from getting dead...).
