When attempting to market a product to women, factory faults are of far greater importance than when marketing a product for the use of men. The latter understand the difficulties of factory production and accept the occasional defective product as a routine. They expect it to be credited. They expect prompt correction on the part of the manufacturer or dealer, and, once adjusted, with them the matter usually ends. Not so with the average woman purchaser. First of all, and last of all, she remembers that something was the matter with the machine for which she paid her money. Oftentimes only the most drastic and unusual service on the part of the manufacturer will take away the sting that was left in her mind by the original transaction. In club, church, or in confidential chat at home, somewhere she leaves the impression that there is still something the matter or she would not have gotten a poor machine. The advertising value, therefore, of a uniformity of product cannot be overestimated. No amount of costly after-service will compensate for the lack of it. THE VALUE OF PROPER DEMONSTRATION BY THE DEALER. A manufacturer sometimes fails to satisfy the woman consumer because he is attempting to satisfy a dealer's demand for "flashy" rather than practical selling points and, therefore, loses sight of the value to him of a perfect functioning of his device. Exclusive points of design that can be used for a spectacular demonstration have been up to this time perhaps the strongest of selling aids; but manufacturers and dealers alike are beginning to realize that they have an element of danger. Thus, the confetti test for vacuum cleaners was an unfortunate misuse of the machine. It has never convinced the woman purchaser that it would accomplish the more trying task of removing "grimed-in" soil, even while it fascinated her as a spectator and even while she left as a purchaser. She doubted her own machine because of the unconvincing test.
