Warranty tolling means that everyday that a product is in repair under warranty, not including shipping time, the warranty is extended to match those days. Think of it as giving products snow days, with snow days being repair time.

And I don't know really. I just use it and not think about it. It went in for a red ring but I'm not worried if it'll do it again. *shrugs*

Point is, things break. Some a lot more than others. Skydivers don't let the chance of death keep them from getting that high, you know?
