Wow, just incredible props for getting this over the finish line. As someone who has manufactured a purely mechanical product, I can't imagine the hassle dealing with factories on this. They absolutely hate doing anything they haven't done before, especially if the tolerances are tight.

The products are right up my alley too, though I'm all manual at this point. I hope the Trefolo and Turbina are both so wildly successful that you end up making manual versions of both. :)
