I like the fact that he might do a 3D cad drawing for you. You would think for a price of 540K he would at least throw in the CAD drawing without you even asking for it. Does he think the industry is big enough to justify this kind of price?
How are you people taking this seriously? You looked at the "item specifics" section, saw the category "weirdness" and saw that the answer was "none," right? Not to mention that he came up with his idea in two days...
I don't think he's a tool. I think he's hilarious in all sorts of ways.
I can understand he probably does not have money for a prototype.But a CAD drawing? After splashing out 500K you then have to wait 3/4 weeks? I think not. If it is such a great idea he should do everything he can to patent it and then try get a backer. Who the hell is going to splash out that kind of money on somebody elses idea? AND you don't know what it is.Can't he see how ridiculous it is?
