Metolius Gatekeeper Locking Carabiner

Does well at keeping the carabiner from rotation while belaying. The spin lock is OK but doesn't turn as smoothly as others. The paint on the carabiner wears off almost immediately, and grooves from the rope appear faster than expected. This is a nice design for preventing your carabiner from rotating while belaying. It attaches to the harness more easily than the other gatelock style carabiners I've tried. However, the green paint wears off from the rope almost immediately. Mine has no paint left… Full review

Edelrid Pure Slider

It's an easy to use and lightweight autolocker, perfect for a more secure alpine sling or to use in anchoring. I bought four of these mainly to use for anchoring and having secure carabiners for whatever I need them for. I can easily open them with one hand by putting the spine in my palm, and using my middle finger to push the slider down and open the gate. There could potentially be a scenario where a rope or rock can do this as well, but you'd have to pretty much purposefully place it in a situation… Full review

Black Diamond Mini Pearabiner

Great all-around carabiner. I really like this carabiner. I used it only for belaying because is not that big or small, so I can use every kind of rope, specially when I'm doing multipitches. Full review

DMM Belay Master 2

Excellent product, vey well designed and made. it's perfect for the job (belaying/rappelling carabiner). Bought the Master 2 exclusively for my tube-type belay device and love it. I've used it now for a few weeks and plan to get a second one soon (backup in case of loss or theft). The "pivoting catch" assures me that my 'biner is locked properly and will not cross load whether belaying or rappelling. It's foolproof because of that folding catch and thus provides visual peace-of-mind for me and… Full review

DMM Revolver Screwgate

Great little pulley biner combo. The revolver is a great piece of kit for top roping and glacier travel. It cuts down on rope drag, and it is essentially a built-in pulley, which gives you a huge mechanical advantage especially as a secondary part to crevasse rescue kit. Only complaint is that it won't work with a Petzl Tibloc. Prussicks seem to go fine. Very durable and while the gate opening is a bit narrow, it is easy enough to figure out. Full review

Black Diamond RockLock Magnetron

Large auto locking carabiner. Not worth this girl's money. I purchased this biner because of its size and the magnetic catch. I like a larger biner for a double line munter (as a backup plan in case something goes wrong with my Reverso). I thought it may pose a problem for ice but that was not the issue. The magnetic catch is not an ergonomic fit for me. I have small to medium woman's hands and when I reach for release it is just out of my grasp. Only by millimetres! What a pain in the butt! I then… Full review

Simond Spider Screwgate

Lightweight, excellent screwgate locker that has a perfectly shaped nose to make clipping extremely easy. The best locking beiner for personal anchor systems at the top of a long difficult route. This carabiner is the best I have used to attach a personal anchor system at the top of a route. The nose is shaped in a way that it is quite open (bent out) compared to other screwgate lockers, so clipping is extremely easy. The diameter of the carabiner is around  a medium sized thickness. Since the… Full review

Metolius Element Belay Carabiner

*Dislike. I marked this biner, used it once, and retired it to the shelf. Thankfully, I only bought one. The gate takes too many spins and it doesn't spin freely.   Full review

Black Diamond Mini Pearabiner

Easy to lock/unlock. One of my favorites. I can lock/unlock this with the flick of a thumb.   Full review
