I have been shaving with my Apollo Mikron on a setting of '2' and it's doing a marvelous job! This is one hefty razor but it has wonderful balance. What I like so much about this early adjustable is that the settings move smoothly from 1 up to 8 with no divisions. I could very easily set it to 2.25 or 3.5. I don't have the guts to try it on '8' but I am guessing it would be like shaving with a straight razor!
