The intro video does a good job of explaining what's happening here but, I still have to write a minimum of 150 words. So, here goes: some nights I take a prescription sleep aid because my schedule gets all screwed up as a result of waking up at 3 am. I don't fall asleep immediately but for the 30 to 45 minutes it takes to kick in I will have no memory whatsoever the next day. Whatever happens in that time period is a complete blank. If it turns out that I did some on-line shopping when the stuff arrives five to ten business days later, I have NO IDEA WHATSOEVER what it is. So, unlike other un-boxing videos on Youtube, I have no clue what I'm about to get.
