I mostly skipped through the first video segment but stopped briefly at each item shown. The camera operator needs to cut down on the caffeine before filming...I was getting vertigo from watching it.

As for the contents of the kit and the reported cost, one could do much better by spending an hour or two researching kits on forums such as here and they would have a much better, all around kit in the end.
