Earlier quoted context omitted.
Mine "taught me" by handing over a cheap electric shaver and basically saying "you can't go wrong"... I think you can change the blades but he never did, so neither do I, just wait for the entire thing to break or get lost. So all the debate around what's cheapest or most manly has always somewhat confused me.
How well they work really depends on your beard hair. I get a pretty coarse, thick beard and quickly discovered electric shavers were a no-go for me.
I still use electric. But the trick is to buy a beard trimmer. Trim beard with that, gets you to pretty short stubble, then you use electric shaver to go clean shaven if you want. I actually have found stubble to short beard to be ideal spot for me.
