Review (2/5): wait a sec. definitely not a 4.5 star.
Out of the box, this was a disappointment. The motor was weak and it barely shaved any of my moustache. When I turned this on, it honestly felt and sounded like another shaver that's at 5% battery level. I was beginning to think that mine was just a defect but then decided against doing anything because the rotary type did not seem to be a good fit for me. I don't have a thick beard, and the shape of the shaver doesn't work well for cutting above the mouth hair.
this looks ok, but it feels light and cheap.
