Review by Troy Good Features Plenty big, the autolocking biner is easy to open one handed once you get used to it, and the other version with the yellow gate is great at not freezing up when ice climbing. Bad Features I've got mixed feelings about my autolock Am D. One time when switching from ascending to descending gear, on rope, I accidentally cross loaded the gate with my descender (a rack), and I broke the plastic gate... which caused me to fall. I normally took it while doing ropework because I can open and close it so easily. Now I don't use it anytime a rap is possible.
Since my accident they've changed from a plastic to a metal gate, which makes me feel better. I still wouldn't recomend cross loading it, but its prolly stronger. I still have several of the older biners that I still use, so I still trust them... I just can't help but think if that had been a normal biner I wouldn't have fallen.
In conclusion, this is a great biner, but don't be stupid like me and crossload it.

Review by marks Good Features The screwgate is excellent. Very smooth and easy to use locker. Bad Features The autolocking with the green ball is just annoying. Sure you can't unlock it by mistake but unlocking it period is a pain (especially if you only have one hand available).
Comment by Troy Mark, you're nuts... I can get my autolock Am D open with one hand easy.
Comment by Troy The secret is to put the spine towards the palm of your hand (like how you hold a non locking biner before you clip a bolt) and reach across the biner and open the gate that way with your thumb and whatever that third finger is that isn't a ring finger.
Review by tande140 Good Features With the Ball Lock, there are NOT any good features Bad Features This is the most worthless carabiner I have ever been cursed with. A friend gave me a bunch, and I leave them on rappels. The Ball Lock gets dirty and doesnt work. DO NOT BUY THE BALL LOCK! Recommended Alternatives any other carabiner on the market
