The shite that burns twice as bright lasts an eighth as long. No, wait...
"Several of Dyson's hallmark products are more energy efficient because they use more power for a shorter period than conventional products on the market, some of which are made by German rivals including Bosch and Siemens."
This has indeed been my experience.
The Dyson my wife bought died after 18 months. The German-made appliance I bought (that she wanted to replace with said Dyson) is still kicking after 13 years.
The Dyson was definitely using power for a much shorter period than the German thing.
