Fair review.
I've sold my remaining Headblades that were worth anything and threw the rest of them and the product line away.
The Mach 3 gives me a baby smooth shave, no gimmicks, no hassle, virtually foolproof and fast. The added bonus is that I don't have to switch razors to shave my face, around the ears, etc.
I gave everything a fair trial, from 1800's razors on up to the latest and greatest products - including one that isn't available in the US by King of Shaves.
Bottom line for me, simplicity, quality of shave and function won out over clever designs - no brainer really.
Every now and then I still whip out a 1940's Gillette Super Speed, badger hair brush and some luxury shave soap just for the nostalgia of it.
