Title says it all. I'm talking strictly impact sockets. I bought a set of 1/2 semi deep 15-27mm snap on impact sockets, (the them I was suckered into a sale, and I HAD to buy something lol) I heard they're the best. But the drive end seems to round out super quick. Also noticed my Matcos are thinner, and seem much more sturdy. At least to me, what's your opinion?
