Loves these carabiners for the lightweight smaller-mid size!
I bought a bunch of these in time for a few weeks of canyoneering in Southern Utah. I usually carry a few of the Mammut workhorse carabiners for when I want big carabiners (like using a sandtrap or rigging rappels) and I like to carry a bunch of smaller lightweight ones for PAS's, clipping things to our packs, clipping rope bags to our harnesses, and generally all clippy type needs in a canyon. These are lightweight, strong, have the orange warning if you are not locked, and open wide for the small size. Great carabiners and I will probably buy a few more in the future.
Super light weight
It's pretty cool. I'm still alive so that's a good sign.
My favorite biner ever!
My favorite carabiner I have ever owned! When its time for a D locker, this is always the first one I look for. On several occasions the bright orange anodizing has come in handy when I drop it in the leaves or grass, and the orange indicator on the gate is always reassuring. I have noticed that in particularly icy conditions like a frozen waterfall or freezing fog, it sticks pretty badly, but only in the nastiest. I use these for my rappel device, for my quad anchors, for my personal anchors, anything but a munter belay! (but would Totally work in a "pinch")
Slight and effective locking carabiner
The locked indicator is great for a quick visual check. Use them for anchor building
Great locker
Small, lightweight, and has orange on the gate to indicate if it is open or locked. Plus the screw gate is smooth, really liking these lockers. Edit 12/23/23: On a wet day on the ice this month the gates on these froze and were prone to sticking. I was able to easily unlock them which was a bonus, but even after unlocking the gate itself required some work to get open. I did not have this issue on other carabiners that also have a color lock indicator.
Good locker
I've used this a few times for glacier climbs. I like that it's easy to tell when it's locked, thanks to the orange coloring on the gate. Highly visible in general, assuming your stuff isn't all orange. Good action and not too heavy. Not much else to say, really...it's a locking carabiner! Good for climbers of all levels, or anybody wanting to secure themselves or their gear. Mammut makes great stuff.
LIGHT
These lockers are really light. I would recommend they find a way into your rack or standard gear. The red unlock marks you feel like a simpleton but they are idiot proof. Great for new climbers to focus on that detail and feel an additional layer of security even if they know nothing else.
Solid carabiner
This is a solid working carabiner. I wouldn't use this to create anchor points or belay from it (although you absolutely could) I've just been using them for work loads at my gym I work at. It's small and works perfect for the tasks I use it for.
Very light weight and versatile locker. Super nice for anchors and it can be used with belay devices. The indicator is also nice for paranoid climbers, if you don't see any orange, the carabiner is locked!
Great locking biner
Works just like any locking biner should. I would give it 5 stars but with under 50 uses it has already started to become a little sticky. I don't know if I got a faulty one but overall it works great.
