I discovered this while travelling. The oil is odorless and colorless, and you only use 5 drops to shave with. It was hard to believe, this was going to work, but I got the best shave of my life. Since I can see what I'm doing, it's very easy to shave around my moustache and beard. Plus, there's no clean up afterwards--just wipe my face and I'm done, and my face feels great. The tiny vial takes up no space in a suitcase or toiletries case. I have shaved with nothing else for over 3 years, currently using a Gilette Mach-3 Turbo, and I get no razor burn or nicks, even when I go over the same area multiple times in different directions. I have given Shave Secret to at least 5 frieds, and they all liked it, too.
