Query: Boo...

Ordered this for my 9 year old step son. He was super excited to receive it, but when it got there, it did not work. No lights, nothing.I didn't want to chance buying a new battery and having it "work" for a few days and then go bad, so I immediately sent it back.Bummer, because he had an Ironman kid's watch at one point and loved it, and this one was a decent price.
