My trusty old Remimgton 3 foil shaver is finally failing after 20 years. They haven't been available for years, and replacement screens have gotten expensive and harder to find. So, I'm shopping for a replacement. The 2 head F5 seems reasonable at $53. Anyone have one of those? I tried a couple of the rotary headshavers, and they just didn't work for me, so I sent them back. I razor shave daily, but sometimes I hit the sides and back with an electric first.
