I purchased this mat to use on a carpeted floor, under my Schwinn 430 Elliptical. I'm very happy with it. I was afraid that the vinyl might tear or become stretched and misshapen from the weight of the machine, but it is thicker and more durable than I expected -- it feels like heavy rubber. I was also worried that this mat might have an unpleasant odor, but no problem with that either. Finally, since I have it on a white carpet, I check frequently to make sure it hasn't stained or discolored the carpet; again, no issues. In conclusion, this is a fine product for the price and I would recommend it to anyone who needs to protect their floor from the weight of the machine, and their exercise machine from dust and static.
