On the bright side, my DH can verify that Sears really
does back every Craftsman tool with an unconditional replacement or money-back guarantee. Or they did in the 1970's at least.
Because I'm very certain that: 1) marine deep-cycle batteries, 2)four of them, 3) in series, 4) car jumper cables, three sets of those, and 5) both terminals, was NOT what that item was intended to be used upon-- but they did apparently replace that 28" wrench no questions asked.

Apparently the tennis-ball launcher was a different matter, once home-brewed napalm had been used too liberally.
(No, I'm actually not joking).
Each of us nearly burned our childhood homes down at several points. DD lit a few things on fire, too. I recommend keeping smoke detectors and fire extinguishers on every level of one's home.
