I flinch every time I buy Gillette Proshield replacement cartridges. Because they cost too much for what I’m getting.
The first shave is always very pleasurable, granted, but you can feel a very slight diminishment during the second shave — not as sharp or clean. And the third shave is the same or even slightly worse. The fact is that cheap plastic razors (also made by Gillette) work almost as well over the course of, say, eight or even ten shaves.
Why do I keep shelling out for these shitty, over-priced Gillette cartridges that are good for only one great shave? Because I like holding the metal Gillette shaving device. (What should I call it?) It feels good in my hand. I like the weight of it, and the little grooves and micro-bumps allow for a better grip. Otherwise the cartridges suck eggs.
