OK, in my experiance, almost anything with a lifetime Warentee is in good shape. Then again, im still young. However, i have had to just replace a Craftesman 3/8, 1/2 rachet and a snapon 3/8. However, i have a SK 3/8 that will not break. I Blew Up a Craftsman 3/8 Trying to remove my O2 sensor on the Cutlass. My SK got it right out, no problems. Now Craftsman and Snap on may be easier to replace, but when you dont have to replace them, why worry?
