Its no secret that older Craftsman tools are better made than the new ones.
FWIW, I have a complete set and a half of G2 or older sockets that look new and have never failed. I also have a few of the newer laser etched sockets in my trail box that get tossed in the sand, go to the beach and get generally abused when I get pissed at my truck. They still look good and are holding up as well. I would say you got some bad sockets.
The reason threads like this get out of control is because people like Merkava use this as an excuse to claim Craftsman is junk and you should buy what he buys. You don't see me starting threads every day to show how great all of my tools are, so of course this makes Craftsman look bad. And Merkava apparently lives for this.
I think iandh actually had a thread about CMan sockets awhile ago that I got pretty heated about. One persons, or even two or three, bad experience doesn't make the brand junk. Maybe they need to start paying a little more for quality control, but that also means us paying more for their tools. I think I'll just live with exchanging them.
