Can't say I remember the last time I shaved with a Mach III. Prior to breaking into straight razors, there was a couple years where I was a SE and DE safety razor user. Prior to that a couple years of no shave at all (i.e. the Bobo the Homeless man look.) And prior to that, I was in the military and used a Mach III so I guess it has been at least six and a half years or so. I have no beef with the Mach III or anyone who chooses to use one but I'm not sure I understand why you would do so knowing that more effective alternatives exist (i.e. Gem 1912, Gillette Fat Boy, or any straight out there.) If I needed a travel razor it would likely be one of my safety razors but hey ultimately it's your shave, your choice.
