I've got a Mach3 but I swear it seems like I only get MAYBE 2 shaves out it before it's dull and shitty. I shave about every other day, or I start looking a little rough. If my facial hair followed any predictable pattern it's probably be easier to shave, but the hair grows in different directions all over my face.

I've tried using all my buddies various beard trimmers and they all seem to suck. It's like it'll cut maybe 6 out of every 10 hairs it goes over so I'm left with bunches of random long hairs all over my face.
