I concur Plank--in one week it will be only 4 months since the first Nunchi patents were approved. To say it isn't selling is incorrect, the fact of the matter is that it has not sold so far in a short span of time. I do not know much about technical stuff, but incurring a big expense on Nunchi is not like going to the store to buy groceries. I would presume that anyone interested in the product would have numerous paces to put it through and testing to do prior to committing alot of money. Is it being sold right and is the asking price right, I have no idea.
