Hi, I've been using a Philips (Norelco) Sensotouch 3D RQ1250 on and off for the past several years. It shaves smooth both wet or dry but a bit harsh for my skull. I have a sensitive skin and used to shave with Mach 3 always with the grain thus no BBS before I bought the Philips. After researching on the internet got myself Braun Series 9 two years ago, great for head shaving and almost without irritation. My shaving routine is wash with a decent scrub, towel dry and wait for the skull to dry fully, apply Lectric pre shave lotion and wait to do it miracle for 15 seconds, then shave with my Braun shaver (the secret is in slow strokes against the grain), when I'm done I wash with cold water and apply after shave balm, last but not least a good moisturizer (preferably with SPF).
Good luck.
