Stumbled upon this guy's stuff, and realized if I hadn't seen it before, not many people have,--which is too bad, as it's a nicely designed, useful system.
I actually called the owner to see if he'd share some of his marketing experiences with me. He was congenial, and it seems like it's been, as one would expect from how hard he is to find/low numbers on his videos, a disaster. He's 87 now, and doesn't have the energy to pursue it more. Jessem's wildly loved table saw hold downs are formidable competition, but his system nicely solves the finish-the-cut problem many complain about.
He spent serious money obtaining patents, and almost certainly didn't recoup it. Funny product name too!
