I, too, was delivered into DE shaving from the cost of the cartridges for this "shaving system". I did use the motorized version of this device and thought it was the best of the best until I went to purchase a new set of cartridges. I did enjoy the back trimmer as it did a great job under my nose. I am old enough to sort of remember shaving with the Gillette DE razors in the 60s. But I was bilked like the rest of us into believing cartridges were better and therefore followed the herd into what was the best innovation path. Now that I have returned to the fold and rediscovered DE safety razors and shaving art form, I feel I have been delivered from evil. Gillette only provided great razors in the past for a reasonable price to keep us buying their blades. It is all about selling a commodity that is disposable that caused Gillette to start on the cartridge quest because others were creating DE blades that worked as well in their razors. They want us to use and only use a product that they manufacture and this is why only their new cartridge blades fit in their latest razors. This is good business sense but leaves us up for grabs when it comes to the best bang for the buck.
