I always had ingrown hairs on my neck from cartridge razors. They increased with the number of blades. It wasn't until 2009 when I switched to DE shaving that my neck cleared up. I don't miss the bad shaves and the irritation. About a year ago I felt the need to try to use a cart, but with DE prep using a brush and soap. I made it fro my sideburn to my cheek and stopped once it began to tug on the chin. I could not believe how bad it tugged. I dropped the cart and picked up my Progress. Smooth as butter! In conclusion, even the first shave from a new cart is uncomfortable!
