Bought it late October 2017 now June 8 2018 and now has cracks in it. When spending over 150 dollars you'd expect the product to at least last 1 year the cheap ones do that for me.

My first impression of this is pretty poor.
All the edges are quite sharp. This is concerning since I'm using this in my home office and usually am not wearing shoes.
This is supposed to be for "for all carpet types", but the spikes are too short to keep this from moving. The spikes are smaller than pictured.

My old chair mat had these dimples where the wheels of my chair sat, and after a few minutes it was almost impossible to move the chair a little bit, it would always roll back into those dimples. I needed a bigger mat and found this one. At first I was skeptical because it was thinner than the mat I had before. The material is really hard though, so it does not make those dimples. It stays nice and flat and I can move my chair by tiny bits. If it had longer prongs on the bottom to keep it in place, I would have given it 5 stars. It moves around an inch or two, so two/three times a week I have to slide it back into position. It is very expensive but worth it if it is as durable as they promise. Time will tell but I have a good feeling about it :)

Not any better than the cheap ones. I spent the extra $ but has only lasted 7 months. I bought thinking the increased cost would mean a better product. But has since cracked, and now I'm left with having to replace.

Poor, do not buy. It is breaking up from chair rolling on it. Bad quality a terrible waste of money.......
