DMM Shadow
The DMM Shadow lives up to its name - an extremely lightweight locking carabiner you won't even notice is there. Slightly bigger than its sister, the Phantom, the DMM Shadow features an I-Beam construction to save as many grams as possible, but not too many that strength or handling is compromised. Extremely lightweight, the DMM Shadow comes in a larger size to facilitate handling, and is ideal for the fast and light climber or mountaineer seeking to shed every gram possible on their ascents.
The DMM Shadow has a choice of three different gates. The Screwgate is a classic manual gate, whereas Kwiklock and Locksafe are both auto-locking. Kwiklock is a two-part gate that requires a twist and a push to open; Locksafe is a three-part gate that requires a pull, a twist, and a push to open.

Strong and light I-Beam construction sheds weight whilst increasing strength
I have two of these and use them predominately for cleaning sport anchors.
While small and light, the beaner is still large enough that it's comfortable to work with, without being a nuisance on your harness.
The locking mechanisms does feel a little flimsy but have not given me any reason to worry.
I bought two different colours and find that having colour coordinated beaners makes keeping track of everything a little easier when cleaning an anchor.
Overall they're light and get the job done.
I've got several other DMM products and always been happy with them. It's a really nice locking carabiner!
One of the best locking 'biner of the market! Why? Easy, it's no big, is not small, it has the right size to clip in a bolt, or multi-pitch at belay station. And really strong! (of course, is DMM)...
It's small (better because not so heavy ) and when close looks a bit like the eye is open...
Best carabiners I have used. Great feel, smooth action.
