As someone who has always used razors to shave only the beard on my face, it would be useful to see more reviews on how it performs in that role, as well as head-shaving.
I might add that I've not come across any safety razor that performs well with a big blob of soap built up on it, and especially not the thick-ish soap this chap applies to his bonce.
Personally, I'm not unhappy that I bailed out of the Kickstarter when it became tiresomely overdue, but I hope that this doesn't cause Rockwell grief, as they surely don't deserve it. At the proposed retail price, I can't see it appealing to a lot of people, when there are a lot of excellent razors (albeit not butterfly adjustables) available at that price. If they have fulfilled their Kickstarter backers, I suppose they'll see what interest they get from the wider market. They raised close on $400k, and I doubt that will have gone into the red, but if they can't make the sales and, more importantly, bring down the retail price to do so, I imagine it will just fade away.
