content: My husband picked this out and I bought it for his birthday last week. I gave it to him Saturday and it was broke by Wednesday (last night). He was using it in our back yard when the ball went flying off. It came with a replacement ball, so initially he thought it could be fixed. However the 2nd ball doesn't stay on, so we are thinking some other piece probably flew off as well, leaving us with a piece of junk.Luckily we purchased through SG and can get a refund (I'm told). He was so excited to use this thing, and loved it the first few days. Such a disappointment...hopefully this can save you from going through the same thing.
