This mat is pretty good the one we had forever finally was breaking and we needed a new one for the office. This one fits perfect for the smaller desk. It seems to be doing pretty well.
This works exactly as expect. The product arrives folded once over which creates a crease that needs some pressure to flatten out but ultimately causes no problems.
These mats seem to be holding up just fine so far. You get some wheel indentations when sitting for a while but not too bad (low pile carpeting). I don't think any of them would be Perfect. Much better than the thinner/cheaper ones we've purchased in the past.
