It was difficult to find a mat this size and without spikes. Now that I have it I am completely satisfied. There is no static buildup or curling. I only give 4 stars because it would be great if this particular size of mat were offered in a complete rectangle shape rather than notched for a desk. To get a full rectangle you have to go to the next size up which is too big for my needs. Otherwise great purchase. I recommend it.
The last chair mat I owned buckled along the edge which made it dangerous because it was easy to trip over it. I don't believe this one will do that. so far I love it! It looks much nicer than my old one has a cleaner look. I gave it five stars because honestly value for price--it doesn't get any better.
