Forget about brand loyalty, what about knife loyalty? Almost every brand out there probably has had some duds, should we really hold that against them? In an ever evolving market I'd say we should not. We should also not defend the duds just because of the name. If something isn't right, we as the consumer have the power to change things if we play our cards right. Blind loyalty will lead to product failures that will keep being produced when the money is still coming in. It is in the best interest of the consumer to spend their money wisely using an objective perspective in every case. In the same breath I would also say that everyone can spend their money how they want, and that's the beauty of a free market; however, nobody wants a crappy product.
