Only one drawback and that is where the packing slip was glued on to the top of the mat. 30 minutes to try and remove it and the glue. Still unable to remove the glue so shoes stick to the mat every time you touch the area where the glue was. Would not buy again only due to this sticker being on the top instead of the bottom of the mat.
After reading reviews for this mat I hesitated before buying. Then I found reviews of more expensive mats had the same poor reviews. I guess people are buying it for the wrong applications...this is for a low-pile carpet...not wood floors or heavy-pile carpets. I expect to get years of use from this product since I purchased it for the proper application So-far so-good.
This chairmat is used weekdays and holds up well for it's heavy use. It doesn't get noticed which is how this type of product should work! We always buy them again when they eventually wear out but it takes a long time!
