Should men use manual or electric shavers?

If you have a thick beard and need to shave every day, you can choose to use a reciprocating electric shaver; if you have a small beard and do not need to shave often, you can choose a rotary electric shaver with a larger contact surface; Men with thick and long beards can choose a three- or four-head rotary electric shaver; men with thicker beards can choose a manual shaver.
