Query: Story Reader Stopped Reading

My 4 year old daughter absolutely loved this. She got it for Christmas and 6 months later it stopped working. She's disappointed and I'm annoyed having invested a lot in the books. She has more than a dozen and they are not cheap. Now, I need to spend another $30 to replace this thing. It's troublesome. I give it high marks for making the kids happy but not so great marks for poor technology that breaks fairly easily. Too bad.
