Query: The "Nightmare" before Birthday

At no fault of the Seller's this product is a piece of Junk!! It came in an unopened sealed package. I opened read the instructions and hooked it up to my computer. After being on charge for 8 hours it would not turn on or work at all. I put songs on it to test and no luck. This was meant to be a birthday present for my daughter who loves Jack from Nightmare Before Christmas. I had to go to Walmart and buy her something else. Piece of Junk!!!!!
