These are not only the cheapest locking carabiners Backcountry.com sells, but they are also one of the lightest that feature the snag-free keylock. The only lockers lighter are the WC Neons and DMM Phantom, which will cost you $3-4 more each, a tradeoff of nearly $.50 per gram saved.

I have owned 4 of them and none have had any functional issues at all, they lock and unlock smoothly and the gate spring is strong and even. They work perfectly in pairs for toprope masterpoints, or alone for clove hitching into multipitch anchors and attaching prussiks to your harness. The silver coating is better for the environment and doesn't blacken ropes. I use them everywhere I need a locker, except as a belay biner.

It is the rare case in outdoor gear that you can save money AND weight.

Same opinion and satifaction as previous reviewers...thought I just add my vote to its quality to help quantify the item.

Light and smooth. 1" tied slings don't sit so well in them but that's the price you pay for light! Also when I first got these (I bought 2) they both had a small metal sliver stuck to the hinge on the gate that poke med. I had to pull it off with needle nose pliers. Then they were great!

Great buy. Great price, lightweight, smooth locking mechanism. Recommended.

I got two of these. One locks very well. The gate on the other only has to unscrew about 3/4 of a turn to go from locked to openable. That isn't a very big margin of error and I'm a little nervous to take that one out just because you have to do so little to unlock it. Other than that they seem very solid.
