B. toys- Paddle Ball Game – Hand Trampoline Set

They're cheap so they aren't made well which reduces how well they work, and have extra features (that don't work, like the top pieces that are supposed to spin while it flies) making them heavy and reducing how well they work further. These aren't frisbees to take and toss to friends across a field, but if you have 4 year olds that are only throwing it 3-5 feet anyways... they work a bit.
