Don't exchange them. The new craftsman stuff is absolute junk and has been for a few years. About a year ago my grandfather decided to trade in a bunch of his old craftsman 1/2 and 3/4 in drive ratchets cause they were just plain wore out, well the new ones last about 4 months before all were junk. Plastic gears, plastic selectors just plain junk. If you have a pre 2000ish ratchet, check with your local snap on rep, they can sometimes rebuild the old ones using the snap on parts. It'll cost you 25-30 bucks but worth it. Again, from first hand experience
