I have 2 Remington shavers (home and travel) that use this system,and have had others in the past 15 years or so. They were great.The latest foil & cutter sets use a slightly differently shaped cutter, and the foil doesn't seem to fit quite right on either of my shavers. The result is that it takes me twice as long to shave, the system "skips" some whiskers much more often, and the foil manages to abrade my skin like it has tiny burrs all over it.Total junk. I'll try one more set to see if they've solved the problems. If not, my Remingtons go in the trash and I'll never go back.
