Myung-Jin O.wrote a review of Metolius Screw Lock & Auto Lock Steel Carabiners on August 17, 2018
Familiarity: I've used it several times
I'm not going to lie about these Carabiners... They are truly solid carabiners. With an ability to take 40 kn of downward force, it's hard to imagine these guys getting beat up too harshly. That being said they are quite heavier than your standard aluminum biners. Great for setting up anchors, but I'd prefer not to use them on sport pitches. Great for the price point!
