I've owned them and used them. And I'll never buy another Craftsman tool again. Right now I buy only Matco and Snap-On tools. Warranty without question, without receipt. Craftsman has told me before that if the tool is not used in their "proper" way, they cannot honor the warranty. With Matco and Snap-On, I can hand them a screwdriver bent three ways, and they'll hand me a new one. Craftsman ratchets suck. I've busted my knuckles more times than I care to remember from gears letting go. I've had Craftsman screwdriver handle spin, wrenches break, etc. I grew up on Craftsman tools, and I'm set to inherit a very large collection from my dad that I doubt I'll ever use.
And yes, I do pay more for Snap-On or Matco, but I don't have to drive somewhere, and they come through the shop at least twice a week, and have even delivered to my home.
