What is the difference between a manual shaver and an electric shaver?

Beards give many boys a headache, especially boys with fast-growing beards, which are shaved before going out in the morning, and grow back at night when they come home.
In order to shave, there is such a thing as a razor. Now razors are also divided into manual razors and electric razors, so what is the difference between these two types of razors?

1. Use time:
Anyone who has used these two types of shavers should know that no matter how skilled a manual shaver is, it takes six to seven minutes to use, while an electric shaver can be done in two or three minutes.
2. Cleanliness:
The blade of a manual shaver can be more close to the skin, shaving the black stubble that is difficult to see with the naked eye to the greatest extent, while the electric shaver is still slightly inferior.
3. Safety issues:
Since the manual shaver is the most suitable for the skin, if one is not careful, it is very likely to scratch the face, and the main feature of the electric shaver is safety.
