Review on Gorilla Grip Non Adhesive Absorbent Waterproof by Tara Wilson

I bought a 24x40 to put under my kitchen sink and paid about $10. I cut it to fit around the piping. The bottom is made of rubber-like material while the top is made of felt. I have confidence in its ability to absorb a small leak should it occur. Also, the bottom is non-sticky, which I think is better because it doesn't leave a sticky residue and you don't have to try to align it precisely. It doesn't slide easily because the rubber bottom "grabs" the bottom of the case. There were a few creases on the packaging but they smoothed out easily when I installed it yesterday and put a few heavier items on top - as you can see in the photos. I will be buying more for the bathroom later and would recommend this to others.
