Don't you love how razor companies compete with each other to see how many blades they can fit onto a razor?....mines got like 5 blades plus an edging blade on the back...fucking things about an inch wide!!
As for the vibrating blade thing...fuck knows what that's meant to do...give a closer shave or something... Looks cool and though..mine turns fluorescent blue when u switch it on!
I hate wet shaving though - it hurts like hell! I use an electric shaver, then go over that with a razor to remove the rough stuff.
