Beautiful, but imperfect
This carabiner has the expert craftsmanship I've come to expect from Black Diamond. I bought it specifically to rack my stoppers on, as I don't like the standard Ovalwire and wanted a keylock with a big basket.
Pros: Pretty big, square basket. Distinctive (and beautiful IMO) color that makes it easy to ID. Keylock means no snags
Cons: Weak gate spring so it opens accidentally sometimes. Heavy. About as expensive as non-lockers get. Lower basket is not that much bigger than a positron.
Overall, not a bad carabiner, and probably super nice on the bolt end of sport draws (its intended use). That said, you can do better for the dough.
Disclaimer: I only own one of these, which means it is possible (though unlikely) that the weak gate spring is an isolated issue.
