Review title: A poor copy, not a used original
Product review: The video came on time and undamaged. That was the only positive. This video is not a used original but a poor copy. I suppose that is the risk you take when you buy "so called used video"; some, like this one, turn out to be copies. I do not recommend buying this video from this source.
