Update: First shave last night. No more cuts than using a disposable/multi-blade razor. I was a bit cack though, took me a little while to get the technique, and will probably take me a bit longer to get the confidence/technique for the jawline.
What I noticed:
-Stubble softness and lubrication is much more critical than for disposable razors. No half measures or you will get rash.
-Bejeesus! It’s possible to get seriously smooth skin, smoother than any previous razor I have used.
-You do seem to need good technique to get a good shave, but it doesn’t seem too hard to learn (so far)
In summary: I am impressed, and it sits well with my self-imposed neo-luddite persona. I didn’t even know you could still buy razors like this, why wasn’t I told before?!
