I had to warranty an old Husky socket so I called Stanley (actually Husky and got Stanley) and they didn't have that socket in stock, so they sent me what turned out to be a Proto 30mm impact socket. I wasn't sure what I would be getting, but I was happy it was a Proto and it sure is a nice, well made socket. I was surprised to see that it was stamped "No Warranty" though. I don't have any Proto impacts, so I have nothing to compare it to, but I wasn't expecting this to be stamped right into the socket. I'm presuming there is no warranty on all their impacts, but maybe its just on the ones they've warrantied out, but its hard to believe that they'd change the tooling for making warranty replacements. I jut found it interesting and thought I'd share.
