I have bought through the internet a portable DVD. I was very excited about my purchase since it was a Christmas present for my son. Unfortunately, I does not work. I have tried several times to use it but it won't. I place the disk, it won't read it. It says, place the disk.My son has felt very sad about this incident. I live overseas and I am going through the hassle of returning the item for a refund.I do not understand how come a brand new item can be broken. I hope to get my money back soon in a credit card refund.
