Review on Bertech High Heat Rubber Thick by Matt Conner

A smooth surface is easier to clean than other textured surfaces. Its bottom rubber is tenacious so it doesn't slip on the table. To update. It looks like it will curl up at the edges. On the surfaces I placed it on, it curled up about 1/8 to 1/4 inch around the edges. The top gray layer seems to be shrinking and the black bottom layer is pulling up. I've never seen this with other brands of rugs that we've used. It also absorbed the dark spots from the base of the microscope with rubber feet sitting on it. There is now a brown ring where the legs sit. The previous carpets left small stains but did not collect dark stains. However, this may be due to the quality (or lack thereof) of the rubber feet at the base of the microscope. I am not sure if I will buy this again. If we order more, we'll likely go back to another more expensive mat that was previously used at the store.
