Query: A Disappointment

I bought this player for my daughter for Christmas and I was so delighted to find a player with expandable memory. It seemed like an answered prayer as she continually outgrows the capacity of previous players. However, from the beginning we noticed that the player ate up batteries like nothing. Even digital batteries weren't much better. Now, 4 months later and the player will not stay powered up and I'm finding more and more bad reviews with the same complaints. That expandable space is of no use to us now!
