The kids loved it, we used 2 to cover an entire upstairs hallway wall for them to play on.However, it really needs to be put on a smooth surface. Our walls are not painted with a smooth finish and have many bumps/rough spots, and after a few days these began to peel off, and after a few weeks we gave up trying to keep them up and took them down. This is the nature of the product and I don't hold it against the manufacturer/seller, especially when the instructions say to put them on a smooth surface. We rent or I'd sand down the wall and repaint it and buy these again. I meant to test regular chalk instead of chalk pens and see if regular chalk worked better/worse, but forgot. I will buy these again when an opportunity comes along
