Most locking biners these days aren't much stronger than a quickdraw, but I'm old fashioned and feel quite reassured by the 32kn rating. I also like that they're a decent size. They are pretty light for the strength and beautifully made. The screwgate is smooth and much tighter than my BDs - which rattles a bit. I carry a lot of old DMM gear that still in great nick and it's always been a joy to use.
I bought two of these with the twist lock gate and they are sweet! These are my first auto locking carabiners and they make me wish I had forked out the extra cash earlier. I bought them to try and make roping up with gloves on easier. Rope goes in and out easily, great product that simply works.
