Given the task definition and input, reply with output. Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.

I bought this reader to transfer pictures of my newborn son from my multiple cards to the computer. The first time I plugged the card in, it wiped EVERYTHING on it, even locked pictures. All the pictures that I had of my son's first few days are gone. This reader is worse than useless - it not only failed to transfer pictures, it erased them from existence. Under no circumstances is this product worth purchasing.
