This socket wrench does not match the description. It's supposed to be cold forged steel and looks like a cheap cast metal to me. It also doesn't have black oxide or black chrome, it's just painted black. But that's not the worst, I ordered two to have a spare. One fits over my M12 Gorilla on 1.5 small bore six spline nuts and the other doesn't. I am sending it back and will continue to look for a quality socket wrench. I will most likely stick with the original black oxide finish Gorilla key. My original socket didn't break, I lost it so I'm buying a new one. I'm also disappointed that Revain doesn't do a better job of scrutinizing the items that are sold on Revain.
