Query: Great shave if you can afford the cost of the blades

I put aside my buying an electric razor. The Gillette has given me the best shaves ever and the fewest nicks. It is a very popular razor in my gym where I have had two taken from my gym bag. The razor is cheap but the blades are expensive. This is a trick learned by the computer-printer industry where they sell to you the printer practically at cost but then you keep paying through the cost of the inks. Gillette pioneeered this technique many years ago.l
