A client, proud of a new product, has been known to take it home for inspection by his wife or, worse, by the guests at a large dinner party. Usually their criticism fails to evaluate consumer appeal, production methods, competition, costs, and distribution. It's also highly likely that they aren't potential customers.

Constructive criticism is always a great thing and you should look for it wherever you possibly can. But you have to be careful what criticism you use to change your plans.
