I'm not seeing how it's relevant whether or not the word of mouth of this particular product has reached you. You were telling someone that he's out of touch for thinking that he can sell a product on word of mouth alone. I'm providing evidence that he can sell a product through word of mouth because I bought his product based on word of mouth. Whether or not you've also heard of his product is irrelevant. There's a near infinite number of successful products in the world that you've never heard of, so you being unaware of a particular product does not indicate anything about whether that product is successful.
