I don't think I ever used a tool warranty, on a car thats another story you would think you would have more problems with a tool that cost a few hundred then a car that cost tens of thousands. I know its not the same category but even the paint is falling off the car, good things theres a recall on it but its been 2 years since and they keep telling me I'm on the waiting list. The car is going to turn into a pile of rust by the time they call me
