I used the OXO Silicone Mat in Small for our kitchen for the bottom of our kitchen sink. It fit perfectly and was an added peace of mind when I would use a wine or beer mug that was glass. It helped to absorb some of the clinking that occurs when you add to the kitchen sink itself. I liked that you could cut a hole for your sink drain and the silicone was pretty easy to cut. I saved the extra piece to use as a little holder for spatulas and spoons. Received more out of the product than expected which was a win. Overall the mat has a simple design and easy to use. The added bumps on the back made it easy to move and not suction to the sink base.
