And what, pray, are "weight and design subtleties that make them nice to use" if they aren't build quality?
My current sport 'draws are DMM Aeros that are about four years old. I have a some similar krabs, about the same age and same amount of use, from Austri Alpin: compared to the DMMs they have suffered far worse wear and the gate action has become rough. Austri Alpin is a reputable company and I don't expect their karabiners to break, but to suggest that the DMM ones aren't better built would be ludicrous.
