Should have heard other reviews! However, none of the reviews provided a detailed explanation as to why this product sucks. While they're not sticky, they're slippery too! It's made of slippery, smooth plastic, so it doesn't gain pressure from the weight! I thought it was a sticky bumper type but pretty smooth and slippery flat circles. The glass is completely slippery and unusable.
