Been using Craftsman sockets full time as a mechanic for the last 4-1/2 years.
I just replaced both of my 1/2" 3/8 12 point sockets with the 'chinese' replacements. Didn't really have a choice, the old ones were so worn they would slip on fairly good bolt heads.
I don't have anything against them. Except that its a 1/2 hr. drive to the nearest store.
I do keep a spare 1/4 and 3/8 ratchet in my tool box for just in case, but its nearly 4 years old and the other one hasn't started slipping yet.
I like the convenience of the tool truck coming by the shop every couple of weeks, and do buy from them occasionally, but cannot support those guys like they would like for me to.
