I have several Gillette Super Speeds and Gillette Adjustables and I have always loved them because they shave great, look great and work perfectly forever if you don't abuse them. I have a few that looked like they had been to hell and back when I bought them and they cleaned up beautifully and work perfectly. I have never had a problem with one after cleaning it and now using several of them for over 10 years. Keep in mind they were 40+ years old when I got them! I also love my 3 piece razors, Injectors, 2 piece razors, etc! They all have advantages but in my opinion the vintage butterfly razors were superb with no real disadvantages.
