whats the diff between series 7 & 9?
I've only had the 9 so can't tell you what's the difference and if there's a difference, but what I could tell you, that compared to the norelco/philips round circular blades this kicks by FAR, so much smoother, amazing clean shave and so much faster.
Kind of disappointed that I stumbled upon this only recently.
To top it off, I can relax in bed and have my shaver cleaned and dried free of charge!(Pun intended, yes it charges it for you as well.) Menuchas hanefesh!
