I bought this for my granddaughter in December 2016, but didn't give it to her until her 4th birthday in April. So she's had it just over a year. About 3 months ago, we noticed the music would stop playing after a short period. We end up just tapping the ballerina and we can get some of the music to play. She's very upset and wants me to get her a new one. I'm upset because while this box is very pretty, and perfect for a young child that loves ballerina's it is very small. I feel for the money paid, it should have lasted much longer. I am the one who winds it up each night, not my granddaughter, so I know I'm not over-winding it. I will try to contact Lenox to see if there is some type of warranty, but based on other reviews, I don't think they will be of much help.
