I use an electric razor maybe 50% of the time (if I can remember to charge it), but I keep coming back to a manual cartridge as you do get a closer shave. In the Gillette range, I've been through them all, Mach3, ProGlide you name it. They're all good razors, but when you consider that the ProGlide is maybe 2x the price of the Mach3 for a 5% better shave, I keep on coming back to the Mach3's.
Good quality shave, gets through the hair decently and most importantly it leaves a result I'm happy with. Will continue to buy.
