Spin Doctor tools not guaranteed?

I purchased a Spin Doctors crank puller at an outdoors store when I was a few states away. I came home and used it, and the pin in the middle bent in half. I was using it properly, the metal was just real soft and it was like it melted when I turned it. I managed to get the cranks off, but the parts of the tool came apart as well.

I contacted Performance, and they said they don't guarantee their parts unless they sold them through Performance directly. I guess it is buyer beware then? Just a heads up.
