This is the only place I've ever seen anything bad-certainly to this extent- about the HeadBlade. When I was "researching" the thing, I searched a few places..myspace had a couple sites related to it, and youtube even has a few videos of guys demonstrating its use.
The only negative comments I've seen outside GB, was that it's got a learning curce but once you get around that you have the best head shaves of your life. Thus far, that's proved true in my experience.
Maybe it's just because I got the Sport version (triple bladed, with the wheels), or perhaps the head lube helps a bit? Don't know, but I'm a happy camper with it.
