This could have been great, but it scared my son.

This was great in theory. My son loves balls, so he would love this, right? Wrong. It freaked him out that it moved on it's own when he was a baby. Once he got older, he wanted to throw it because, well, it's a ball. It's hard. It hurts if you get hit with it unexpectedly. Overall, it didn't work for us but my boy has never liked most electronic toys. If your kid does, they would probably love this. Just don't get hit with it when they're older!
