I've always used that single blade razor in which you have to put the external blade. But there's always a chance to get cut because of the structure. I've seen many advertisement of Mach3. So I decided to give it a try.
It is very smooth at skin as it comes with protective layer. It comes with 3 blades and gives you perfect shave in minimum time as it does not leave any hair on face after using it.
This razor is quite expensive as compared to others. It usually get molded with the shape of your face which in turn reduces the possibility of cuts on skin. The best part about this razor is that you do not need to buy new razor everytime as it has cartridge which is available for 165 bucks. The original price of razor is about 280. I just love this razor.
