I dont know much about
Well, in a nut-shell, they performed rather well, but the build quality was shambolic. A completely new product, with no known brand reputation, poor build quality, and at a price far greater than even the most expensive cleaner in the shops, it had all the ingredients for an epic fail. However, Dyson advertised it heavily on television, and once sales were made and people saw them in other peoples homes, so sales increased further.
Dyson of course attributes this to the fact that his cleaner did so much more than regular bagged cleaners. However, humans beings are not always the most loyal of creatures, and a good deal subscribe to the practice of hope over experience. Were it not for this, Dyson would never have persuaded so many consumers to buy his cleaners. An enormous part of his success must also be credited to the desire to want what others have just had, and to be fashionable. In that respect, the Dyson cleaner had a lot going for it.
James Dyson gets my respect, but for what one might term all the wrong reasons. It's not what goes into his cleaner and his journey which wins me over, it's the way in which he successfully convinced a massive percentage of the United Kingdom to buy his product in spite of the odds stacked against it.
