Review by livextreme41 on Aug. 13, 2009
i haven't used auto lockers until the past few months. I like this one. Smooth action, and solid (i really like the rocklock screwgate)
I have not had problems with the gate catching.
It's heavy, but with an autolock, you should expect that.

Review by Bassnick on Sep. 01, 2011
One of the best auto-lockers Ive ever used, and Ive used a lot of them. Nice, smooth action with a good spring and snap back. Great for belaying and rappelling.
A little heavy and a touch expensive for a Black Diamond product.
Check out the Auto-Locking Petzl William biners.

Review by mjwestla on Mar. 01, 2011
Nice big biner, rounded. good for belays.
Have a few of these and have noticed the same problem on a couple that some others have mentioned - the gate sometimes sticks at not quite closed. Kind of defeats the purpose of the autolock IMO. May return it considering how pricey it was.

This is an absolutely bomb proof carabiner. I have three of them (one auto lock and two screw gate). They are easy to use and big enough for belaying, even if you're in the gym and have a belay anchor attached. They're the biggest 'biners Black Diamond makes but are still light. Don't have to worry about any extra weight!
Nothing bad about these biners.

Awesome gym belay biner. Smooth action, durable and sexy.
Kind of expensive. I've seen the gate come open when rubbing on rock on awkward rappel starts while canyoneering, so watch out.

Review by jciccotti on Feb. 26, 2008
standard belay biner; auto-locking
might just be this one biner, but the locking mechanism catches on the gate just before opening. I may return it. Anyone else have that problem?

Review by juliarod on Mar. 16, 2011
great caribiner! I use it to belay and repel all the time!!
the finish was worn away due to the rope but that happens.

Easy to use and smooth operation, great for belay & rappelling...
Weight, but expected for an auto-locker.

love this for sport climbing, and trad, doesn't get hung up on chains or webbing very easy!

Review by ajchocholousek on Feb. 22, 2011
Nice, big, wide-radius 'biner that is perfect for belay setups or usage as a master point at anchors. Big enough for the Munter's hitch. Smooth twistlock, very confident feeling when it closes. Keylock prevents snags.
paint wears off quickly where the rope is sliding, but no big deal. Heavy, but it's supposed to be a big, strong 'biner.
