i have a shavette-i wouldn't dream of using it to shave with! why risk slicing up my face when i have numerous perfecty good razors? what they are great for (and the reason i bought mine) is trimming moustache and beard edges.
I've had a Dovo Shavette for about a decade now and really enjoy shaving with it - also great for taking off neck hair. Not a thing to use if in a rush, though if you have the time, I find it gives a really nice clean shave
I also have a Dovo Shavette and like "shakespeare" agree it is a shave that is not to be rushed and when so done it provides an excellent shave if you take your time.
