Bests & Worsts Reviews from Amazon

*Update March 2015* I ordered the 6mm thick blue speckled version. This is a very durable mat and has held up very well for 4 years. You can see indents in the mat were the treadmill wheels sit, which is to be expected after this much time, but it’s still quite functional. My treadmill is on the second floor and on carpet. The mat has done wonders to keep the carpet from being damaged. After four years the carpet under the mat is in better shape that the carpet that was not covered. I can only imagine how much damage would have been done had this mat not been there. This mat has also helped considerably with noise and vibration. The selling point for me on this mat is that is made in America. The mat is made of rubber so it did put off an odor when I first got it, especially when I left the door closed to the room it is in. But this disappeared altogether after a month. I think the temporary odor was a small trade off considering a foam type mat, which might not be as odorous, would not last nearly as long as this one has. Also you would need a much thicker foam mat to get the same floor protection and impact absorption as you do with a rubber one. Selling point number two for me is that this mat is made from recycled material, which few, if any, foam mats can claim. After years of use I took off the motor cover of my tread mill to clean out the dust (my owner’s manual suggested this) but because of the mat there was very little dust to clean out. I would highly recommend this to any treadmill owner. If you're looking for a serious treadmill mat that will last you, this is the one.
