Update: I tried my first shave last week with the Gillette skin guard on the face with a couple days worth of growth and a brand new cartridge to give it a fair chance. The shave was horrible I did three passes and it left patches that weren't even shaved on my face. I ended up having to do a fourth pass against the grain with my Schick injector type I2. I had severe irritation, but the good news was no ingrown hairs. So for me as a face shaver the skin guard is a no go. I think it doesn't work for me because I have coarse facial hair, and it grows in all different directions. As a head shaver it is my favorite of all my razors.I get 10 head shaves out of a cartridge, no irritation, no blood and gives me awesome head shaves.
