I’ve never understood shaving. Why not just buy a trimmer and trim it down to 1mm? Much more convenient, faster and cheaper. Also there’s very little visual difference - especially now that everything is remote.
I never get irritation from a Braun S3 shaver, but if I use my Skull Shaver on my neck it can leave it slightly red and irritated unless I'm careful.
That works for the most part. The razor is for all the spots where you want no hair at all. I've got a beard and I can shave my neck down with a trimmer and get it really close, but if I want to actually have clean neck I've gotta reach for the razor.
Depends on your beard. I have coarse black hair that grows fast. People with fine blonde hair can get away with a trim. For me, it has to be a choice between a beard and a wet-shave.
