>You show the no-name product/vendor to enough people to get data for it.

You just handwaved away the hardest problem. What is 'enough'? What if the first user failed to plug it in and left a 1/5? Or liked it but left a 3/5 anyways? And what if you show it too many people so now rebranding products and just dropshipping them takes off?
