So far this mat is pretty good. We have only had it for a short while so have not had an adequate time to test for discoloration or breakage due to to getting worn out. So far it is a nice floor mat.
After less than a year this mat started cracking and only got worse. I patched it with clear duct tape which helped for awhile. I know it isn't the top of the line but I was hoping by paying a little more that it would last at least a few years but that was not my experience.
