I'm a beginner with this kind of machine and bought it exclusively for use on my head. After initially trimming it very short with clippers (a clipper without guards—it cuts to about 0.2 to 0.3 in length), about a day and a half had passed and my head had become quite dark.
By the time the machine arrived, my hair was already quite long, and my question was whether it would manage to cut it...
Well, guys, for a beginner and my first haircut/shave with this machine, it came out perfect, as if it had been done with a razor, and all that with the grain. At the end I also applied some rubbing alcohol, but it only stung a little in a few spots. I mean, it didn't irritate the skin. But from what I saw, the replacement parts are expensive, so keep that in mind. You'll be pleased. Just don't press too hard, because the head wears out quickly—that's where a lot of people go wrong, from what I read on forums. It only needs a little pressure, just barely.

I saw it up close at a barbershop and tried it there. The next day I got it; for daily shaving it is one of the top machines and it charges very quickly. Recommended.

By far the best shaver on the market! Aggressive cut! The only negative is that the mesh breaks relatively easily.

I have tried several electric shavers, this one is the closest to a razor shave. If with a razor you get baby smooth skin every 2 days, with this one you need to shave every day. It will become your routine, a matter of habit. On the downside, it is quite noisy.

Very good, it has nothing to do with a Braun I have. I use it for my head. Much faster shaving.
