Query: Poorly made tennis video

I do not recommend this video, it is a waste of money! The video was made by an amateur, and is extremely unprofessional. It appears to have been made with someone's home video camera in a local park. Background noise, poor lighting, and an unscripted presentation all contribute the poor quality of this video. When I was deciding whether or not to buy it, I read some good reviews. Don't be fooled by these reviews, they were probably sent in by the video maker himself.
