That's interesting Greybeard; may I ask where you get your Gillette Sensor - 2 Blade Cartridges from (not the Sensor Excel, which is a different experience entirely) and at what price. I have still got some left (as this is my favourite Cartridge system), but I was waiting until I return to India in order to stock up in bulk. I have tried the DE safety razor, but cannot be doing with all of the paraphernalia that goes with it and like to shave quickly without getting cut to shreds. Spent out on a top of the range Muhle (please excuse spelling if incorrect) c/w soaps, brushes, pre-shave, blades, etc, etc; but found the cartridge razor best for me overall. The Sensor - 2 Blade seemed consistently to give a very good shave and lasts; AND is as good as possible (for a cartridge system) for the environment, as one only needs to discard a fairly small cartridge as opposed to a complete razor etc.
