This is a replacement for an older one which after years of use wore out. I would not have purchased it a second time if I were not satisfied with the product.
I already did a review on this obviously it was lost in your system. For the price it’s a good value for at home offices I suggest however tomhave one similiar with longer studs on bottom to better support thru standard carpet with regular pile
Better than no chair mat but a bit thin unless your carpet is the short/firm office type pile. Our carpet is a little plush and the mat develops dents if I leave the chair in one place for too long.
