You're right, FG.. this is day 3.. (although I shaved it late on day 1). Not much reaction, since it looks the same. The look of no guard vs. a razor is pretty similar. The feel is different, and so far just the wife and kids have felt it. They all liked it. My son just recently buzzed his down to a 1. He has thick hair and will probably take after his Mom's side, but it's cool to see that he is not attached to his hair. (it is a lot more common these days, though).
