Today I tried Gillette Sensor Excel for the first time and I was disappointed.. that it was quite aggressive(compared to the Mach 3) and I had tiny cuts in several places inside and especially in the neck, And now half an hour after shaving I feel that my face is burning and unpleasant compared to the Gillette Mach 3 which the feeling is very pleasant after shaving. I have no idea if the reason of cuts it's because Sensor Excel sharper than Gillette Mach 3 or its blades are more jagged. The handle was a very comfortable and easy to navigate under your nose. the conclusion: In my opinion Gillette Mach 3 is the best razor Gillette has ever produced, much more Gillette Fusion Proglide + Fusion Proshield and also the others razors.
The OLD type is the best razor Gillette ever made. With that said, I think you need a pre-war Tech, which is milder and more user friendly, but still a most excellent Gillette razor.
I've heard nothing but horror stories about those or any other "reel" razors! Besides that, it's plastic, I don't shave with plastic! But I'm OK with you using them.
I don't know about horror stories but I never had so many ingrown hair as when I used any multi blade razor such as a Mach 3.
There were others also. Unfortunately most of the pix are gone. http://www.safetyrazors.net/bandraz.htm .
