Why don't they tell us this stuff when we buy the product? This happened to me with a rotating cutting mat. I bought it and tried it but didn't like how hard it was to rotate. One day I flipped it over and found that the center circle on the back had an adhesive little circle on it. I peeled it off and MY!! what a difference. Now I love it! It took me a few years to figure this out, so don't feel all alone in this.
