The mat travels on its own. I have to move it back to the correct position 10 times a day. I didn't realize this mat did not have the little plastic nubs that dig into the carpet to keep it in the same place. I do not like it at all.
Hard to tell value until I have it long enough to see about durability. The last few I have had started cracking within about 4 mo....but this one is thicker and I hope will last much longer............
