With as much regard and respect as I have for Mark and Nani, I really hate to have to give this tape a negative review. Read the title carefully, since it strictly deals with suspensions. Not suspensions and levitations, no distinction having been made. Very little information given, lots of time showing publicity photos using the Super X, and the construction of same. Hopefully the other videos in his series (not seen by this reviewer) were a whole lot better than this one. Unfortunately, almost a total waste of money.
