I love my big Shosu beachballs, the feeling of them inflating and deflating under me is like nothing else! Please turn the volume down a bit for the pump inflate part - it gets loud. I finish it off with blow inflation, to make it nice and warm before hopping on for a ride. Bouncing and grinding feels so nice, then I ride it to the ground and squeeze every last bit of air out!
