My 14 year old son ordered this frisbee and he's so pleased with it that he bought another one so he could use one on grass and one over concrete. He said playing with a frisbee over a rough surface (concrete) scratches the edges when the frisbee isn't caught. So he wanted another frisbee to use just on grass because over time, the scratches on his first frisbee are rough on his hands when he throws it. The frisbee is very good quality.
