Inverted Keylock? -Yes.
Is this biner a gimmick? Maybe, but it worls like a charm! Not only is the carabiner snag free due to the monofill keylock feature, the angle of the nose is very shallow, making unclipping as smooth as it comes. A welcoming feature when seconding some difficult passage.
Besides unclipping, the clipping works well too, due to the fact that the wiregate is inset a bit, creating a small void in which the rope fits well. The carabiner is spacious enough to fit multiple ropes easily and even a clove hitch fits into the Ange L.
It's fairly lightweight for a full size carabiner too. I love it!
