Review (4/5): Good for the price. It does bow inward on the rough side.
For the price you cant beat it. Only flaw is the rough side is like a "C" shape after use and during use. The soft side have too much material, making the rough side bow inward. Minus 1 star for that. The soft side is useless for me and my wife. The rough side is good but I wish I can replace the soft side with a way rougher one. I wish they made it from a material that is meldew resistant. Because it kinda smell after a few days. Smell does go away after washing.
