The heads pop off very easily and become a serious choking hazard. I’d only purchase for children over the age of five.

The first one arrived & wouldn't light up. Amazon replaced it & the second only lights up red, no blue, yellow or green. They shipped both in an envelope, not a box, so I don't know if the pounding it no doubt experienced in shipping took a toll on batteries. No way to change batteries so I'll never know if the batteries died or it was just faulty to begin with. The ball itself seems to be well made & the dog seems to enjoy it.
