Query: Piece of junk! Do not waste your money!

We purchased this for our daughter last Christmas. It was difficult to get to work at all, and after 3 months completely stopped working. We still had the box, etc but no receipt. I can't believe something in this price range is such a piece of junk! Spend $20 more and get something reliable. I wish I could give it zero stars.
