This mat is ok.  There is a sticky film from the packaging that I can't seem to get to come off.  Its only in about a 3 inch circle, but none the less, I can certainly feel it when I step on in.  Also, the pictures look like it would be gray in color.  It is light brown.  It does say that in the description, but I saw the color and didn't read that until AFTER i had purchased it.  So that was my error...but the color and the sticky stuff that won't come off make this just an OK mat.
