My son who is 5 got this and he loves it. It's very cute how the light comes out the bottom of bat mans' feet! However, it isn't very sturdy as a keychain. The pin in the top does come out, which lets the hat come off -- if we attached this to his backpack as we were hoping to do initially, I think it would get lost within a week.
A cute toy, not keychain. Not sure I'd buy again
