I'd love to crawl inside the vendor's brain for a few minutes, get some questions answered. Like, did you think no one would notice? No? You vastly underestimate the cumulative free time available on the Internet. Regardless, why actively lie? Buying time, or you know there's no way this will ever work, so you're just figuring out your exit? And lastly, though I am no physicist or mechanical engineer, but some quick napkin math says there's no way to make two twists of a human hand turn into 2 minutes of tooth brushing. Are you incapable of the most basic up-front research and design, or did you intend to be dishonest from the start?

I mean, seriously, there is a mindset there that is so foreign to mine that I can't even comprehend what it might look like.
