After a few months of so/so shaving with an electric razor and/or some cheap disposables, I decided to grit my teeth and shell out for the outrageous cost of some replacement blades for my Gillette Sensor. If you've never used a razor with refillable blades, it's pretty much the same business model that inkjet printer manufacturers use: The initial cost of the razor itself doesn't seem too bad considering it comes with some blades already, but when you go to buy refills you discover that it would be cheaper to buy a whole new frigging razor.
They didn't have Sensor blades, so I bought a pack of blades for the Gillette "Mach 3", foolishly assuming they would be backwards-compatible with the handle of the Sensor.
They're not.
And of course, I didn't discover this until after I had torn the box open, so now I have to go buy a new razor to recoup the almost $9 I spent on these stupid blades. Bastards.
