I started at 3 and thought the razor was pretty dull. Thought my angle compared to my DE 89 should be less steep (ie parallel to face) and more shallow (perpendicular to face). Ended up going to 6 just fine, with some weepers around my neck. I thought this was suppose to be adjustable as far as aggressiveness, but I find all the ranges dull.
No instructions came with the razor
Usually the number plate I want is facing the blade side I assume is the aggressiveness?
I also FELT no feedback let alone heard any. I did four passes trying different agressiveness from 3-6. So I'm not sure if its smooth because I started figuring it out, or I did 4 dull passes, with some patches around my face still.
Coming from an EJ DE89 to a Rockwell 6s adjustable, first shave wasn't too good
