I like how it has 10 replaceable blades which is double sided. To install or replace a blade you just twist the head (lefty loosey) then to tighten it back up you twist it again (righty tighty)So it definitely gives a really close shave. When passing the razor on your skin don’t press too hard. Bc it’s a single blade I pressed it not too hard and it gave me a really close shave. And even so I got nicks/mini cuts that bleed for a couple of minutes. So yes it works but be careful!
