Dyson clearly understand that the judicious use of displaying products actually being used works well with consumers. It helps them to visualise what those products can be used for. Its the closest thing to actually having the product in your hands (a tactic that sales people have relied on for decades).
Let's be honest, their products are visually striking too, with strong bold (but simple) colours that grab your attention by the eyeballs.
The inclusion of the price is wise. People naturally think that a Dyson is going to cost a lot more money, so it breaks the myth.
A money-back guarantee is there to take away the risk and concern (it's still a big purchase) and to build trust and reassurance.
And because we consumers are an impatient lot, the next day delivery copy satisfies that nicely.
