Answers:    I kinda have to agree beside answer one. No offense to you or DIY network, but PROVEN rite and effectiveness is what I necessitate to function.

When I see NEW like that I'm repeatedly reminded of infomercials similar to RONCO, "$19.95 and if you act right in a minute...we'll include."

You might do a Consumer Reports bit of research

I believe that it is the new Craftsman crescent socket. I don't estimate it is all it's cracked up to be. New tools own to grow on me, but the make for pious conversations.
