Cons: No keylock gate, does not hold many slings and ropes
The Superfly Screwlock is the lightest locking biner on the market. Other than its limitations (listed below) it excels at most applications at a fraction of the weight of most locking biners. Its main competition is the Wild Country Neon, which is about the same weight but comes with the key-lock design that leads to fewer gate snags. The Mad Rock Super Tech Keylock Screw also scored higher than the Trango and costs less ($8 vs. $12). For the ultimate lightweight belay carabiner, check out the Petzl Attache 3D.

OutdoorGearLab Editors' Hands-on Review
This is one of the lightest carabiners out there. It is small but still big enough to use at the anchor or with a belay device. It excels on alpine climbs where every ounce counts.
There are no major dislikes other than we wish it had a key-lock gate. All the other low scores are due to it just being a small carabiner (it doesn't hold many knots, is not great for belaying a second, etc). We feel comfortable using it just about anywhere because we like lightweight biners so much. But if saving weight is not the most important thing to you, there are a lot of other great carabiners available.
Any time you are obsessed with weight, as with alpine rock climbing, this biner excels. I use it for nearly every locking biner application except for the following, where I use a pear-shaped biner like the Petzl Attache:
This is at the high end of lightweight carabiners for cost. It is the same price as the Wild Country Neon and much more expensive than the Mad Rock.
