I have Remington R8150 for when I need a clean shave look and Philips Norelco QT4070, for 0.5mm and beyond...
Use Philips more often as I am too tired of having irritated face and stubble just looks better than clean shaved greeness...#
I use to have Remington Barba, which is a truly beastie machine... Major problem with it was that the hair was really flying everywhere and it took about 10 mins to clean up whole bathroom.... QT4070 has vacuum so it collects hair, although not all, but it doesnt fly beyond sink.
