i've run across the videos a couple of times. I won't say it's "bad"... I'm sure it works OK, but I'm not sure what problems he's 'solving' that he thinks other similar sharpeners have. A couple of things I noticed... his base isn't very heavy and looks like it'll need to be held or clamped to work. I don't like the design that the clamp has to be removed and replaced to turn the knife over... I think the design of the KME is much better and easier... especially if you're finishing a knife and want to do alternating strokes, flipping the knife each time... that's gonna get old quick.
Also, did you read through the comments? He's depending on funding before considering any other stones... for example, he states he would need $60,000 to provide diamonds, doesn't think a leather strop would work on the sharpener (although later he says he's looking into it), and states it won't work with a FFG, just a few things I noticed.
Personally, I'd look at the KME... IMO, better clamp setup, diamond stones (this alone probably makes the price difference negligible), available accessories, and a more established company.
