Jordan Braswellwrote a review of DMM Shadow Locking Carabiner on June 28, 2019
Familiarity: I've put it through the wringer
my favorite locking carabiner. the gate is ultra smooth way better than any of black diamond screw gate locker My friends like them better then there petzl. The shape is just big enough for any sport or trad climbing need. An it’s ultralight wait make it perfect for alpine climbs. Ive replaces all my lockers with this one an if you buy it you’ll make the switch too.
