If you want something that is heavier than a beach ball and less painful than a volley ball then this is the perfect ball for you. It is dense enough to be thrown without the wind affecting it while being soft enough so that when you get hit with it it won't be that painful. So it is very good for activities like dodge ball or volley ball.The ball I bought was 7 inches in diameter, but there are bigger ones if people want a larger ball. To get an idea on the size of a 7 inch ball, compare it with a basketball. A basketball is about 9 inches in diameter so it is 2 inches larger. To get an even better idea on the size I can't palm a basketball, but I'm able to palm this ballThe materials for the ball was pretty good. It was smoother than I thought it would be. The inside was protected well enough by the foam. If you are thinking of putting small devices in the ball, then I can say that it can handle the shock from a throw. I put a small sensor in the ball and repeatedly thrown the ball at a wall and the sensor was still working fine.The delivery was pretty fast as well. I got it 2 or 3 days after I purchased it.This ball was exactly what I was looking for.
