This is a mobile razor, small and very convenient, you don’t need to compare it with a large full-fledged razor, these are different things, for their size and price, this is a very good device!
Different pros:
Convenient, small, you can even put it in your pocket, it runs on batteries for a very long time, you can use it on the street, it does a good job with bristles!
Different cons:
Hair from 5 mm already shaves badly, but it is not for such beards either!See full review
