This is a great mat for the price. The only glitch is that it was rolled up when I purchased it and I had to mess with it so it would lay out straight. It is totally fine now and I'm glad I went with it vs. another more expensive mat.
The short "cleats" while more comfortable to handle do little to keep the mat in place. The former mat was much more stable. The ad also mentioned a warranty but no such info came with the mat.
