I picked up a mirror today at bed bath and beyond--they had several fogless mirrors but they are all the suction cup kind tat yu put on the shower wall--not familiar with a handheld one myslef...
Anyway I can honsetly say that shower+mirror=my best headshave yet...It is amazing how much more glide you get....
I've always been a shower shaver with a mirror. When I travel, I can do it by feel but it takes me longer and I have to be more careful. I prefer a mirror.
Definitely get a better shave in the shower though.
just tried it out. definitely a nice shave, but i'll need a mirror i think. practice will make perfect tho
For me, and cleaning off the head is very personal, I have found that shower shaves feel great--I'm a braille guy in the shower--but there's nothing like all the equipment, shaving cremes, etc. of a mirror shave for a long lasting shave. Now what I'd really like to try is a Hot Babe Shave [in my dreams--yeah wet dreams are possible at my age--]--but since my wife is a no no on the subject, it will remain a fantasy. Oh, what a fantasy.
To make sure the mirror is fog free during your entire shower, use a little shower gel on the mirror to clean it off every time you shower. Will never fog on you. Also spitting on the mirror and rubbing it around also prevents the fog up!
Shower shaver here too... I hate to admit I gave a bro here a hard time about the spit on the mirror thing but it really does work!

Google "shower mirror" or "fog-less mirror'.
I have shower shaved for over a month now and I tried sink shaving the other day, honestly I can't say id go back to sink shaving its awful and it my head turns into a forest of irritation. I just got some cheap 1 dollar hand mirror form the dollar store, it fogs up but I just rinse it while im in the shower and it doesn't give me any problems.
