pretty much all tools are guarenteed. its just how you go about getting them replaced. i choose craftsman only because its easier to get your broken tools exchanged and without question,ever. if i break my snap-on matco etc i have to wait for the truck to come o my shop every week to exchange it or find a truck and do it that way. craftsman i just go to the store and get new stuff. but if you dont mind waiting for the truck its not a bad deal you dont have to go anywhere, they come to you AND work out payments
