Weak and heavy. Buy something else.

These may have been state-of-the art in the 60's, but there's no reason to buy them anymore. Why-oh-why is BD putting out a non-keylock solid gate biner thse days? You can get lighter, stronger, and more useful biners for a lower price. I do keep two old ones on my rack as "leaver-biners", for the sole purpose of leaving behind if I have to leave gear and retreat.

Good little workhorse

I like the oval, use it when making top rope anchors or hauling gear,but really small opening.

Nasty, spend your money elsewhere.

I don't get how BD, makers of generally kick-arse gear keep putting out this oval. It's action is always rougher than it's main competitors, it's still got a hooked nose and a shitty gate opening. I'd have given it one star, but I've had the displeasure of using the previous model faders oval, which in it's screwgate incarnation I swear had a gate opening of 8mm. So I gave the BD oval 2 stars for being less shit than that. If you're saving pennies, buy kong ovals, if you've got the money, buy petzl ovals. If you're buying it as a gift for someone you don't like and will never climb with, maybe buy the BD.
