It was a gift from Santa, so a shame it didn't work. It buzzed when received so I wanted to return it but then it started flashing continuously, on the 5th day it wouldn't connect. And it doesn't work at all. On closer inspection, it has some sort of market writing hidden by a small sticker in the battery area. I can't help but suspect that this somehow identifies a damaged item that was resold to me. Disappointed I have to go through the return process, especially from Santa! It will be difficult for children to explain!
