My last one lasted several years but cracked. This one feels better quality and is very easy to roll around on. I bought a second one for my Mom and she loves it (she's in her 80's and can't believe how easy it is to roll around on her office chair now).
I use this product at my desk in my office which is carpeted. The mat is well constructed smooth ample in coverage of carpeting. I use to roll off the old one - not with this one. The only con is the pointed projections on the bottom of the mat are VERY sharp - be very careful when handling.
We put in a new carpet and I have not been able to locate a desk floor mat that did not slide. I was hopeful this one would solve the problem and it did not --- it was also more expensive than the cheaper failures
Needed a mat that was not too big to place under my computer chair. Use this chair approx. 2 or 3 hours a day. Mat is meeting my requirements for ease in moving chair around on the carpet. Price was OK too. Approx. $30 plus tax.
I wish it had been[...] "unrolled". I ended up with a pretty bad bruise on my leg trying to unroll it. Otherwise I am very satisfied with the product. It does dimple a bit but not enough to make it difficult to roll the chair.
