2-3 months in, 80% there...
God, I'm SOOO close! I can get 80% of my face BBS now with 2 passes. The lingering issue is the ****ing bottom 2" or so of my neck. The hairs literally grow sidways/outward. I have not figured out a way to position the razor to shave against the grain there. The length of the blade just doesn't fit between my chin and chest. Best I can do is a few additional passes perpendicular, but that doesn't get BBS. But I'm very happy to say, that I can get an amazing shave now from the adam's apple to the sideburns in 2 easy passes. Upper neck/jaw took me a few weeks to learn, but now it's nothing. I actually grab most of that as I'm coming down from the cheeks.
This probably sounds stupid to most of you "old timers", but for us newbies, it's a good feeling. And I'm still amazed at how long the straight shave lasts. I shave every 24 hours, 7 days/week, and with the DE/Shavette I would have noticeable growth before that next 24 hr mark. Now I'm questioning if I even NEED to shave again because I could probably go another day without anyone noticing I didn't shave.
