Got my gear in today, and had a nice afternoon shave to celebrate.
There was some trembling to start with, but after about 5 minutes I stopped thinking about what I was doing and just *did* it. Very zen. Didn't realize I was even shaving until I finished the pass. I did a modest 2 passes WTG and called it good. Even just with that, it's as good of a shave as I ever got with a cartridge. No nicks/cuts/weepers, either!
If this is the result I get after just a first-time newbie shave, then I'm sold!
