I've used this material in a couple of racecar trailers and I have a large piece in my garage as a mat over my epoxy floor. I bought the first stuff from Sam's and the second time from American Garage Flooring, a BLT distributor.
In the first trailer I used the ribbed style (no "for her pleasure" jokes, please). I found I didn't like the texture of it because it was hard to clean. You can only sweep in one direction and oily grimy bits are hard to get out of the grooves. Otherwise, it worked pretty well, though it did move around under the racecar's tires as it shifted during transport. It was the cheapest end of the range (meaning the thinnest) and had little of its own structural rigidity, which means it did move around pretty easily.
I used the coin style and the thicker type (they call it "Industrial Grade") in the second trailer. It is much easier to clean and does seem to lay down much better, but it will still move when a tire is turned on it. I used the adhesive that they sell and found that is isn't all that great. It doesn't really glue it down all that well. It just keeps it from shifting. When I installed it it was a bit wider than the trailer so I ran the excess up the walls a few inches on each side. I glued that with some adhesive that I had left over from putting vinyl baseboard in the garage. It stuck much better.
I have a fairly large leftover piece of the Industrial Grade coin flooring that I put in the garage as a work mat under the racecar when I'm working on it. The underlying epoxy floor kept chipping under the floor jack with weight on it, then oil would get to the old concrete, etc., etc. The mat prevented that. I've found it works fine under a floor jack and jackstands. It is very resistant to most chemicals and oil, though if you leave oil on it for a long time it will pucker a bit. It doesn't have the structural rigidity of some of the really thick tile stuff, but for the price it does a good job protecting your floors and it is easy to clean. I'm pleased with it in my applications. I don't think I would do a wall-to-wall application in a garage, though.
