I have a series 7 that works great! I use it 1/2 the time and a blade the other 1/2. Keeps me from getting too much irritation and gets as close as a blade initially. The shave doesn't last as long as a blade but then again I can shave dry with it whenever I want so touchups are a breeze. I tried the panasonic but it was too intense for my head. I highly recommend the Braun but I would go with the series 7.
