Dyson seem to be the champion of turning a cheap effective device that's well understood into the same device but an order of magnitude more expensive. Are people still buying it?
Here I am in a hotel room with a Dyson fan, which simultaneously moves less air, and is more noisy, with a much more piercing tone, than my home fan with blades that I bought for £30 from screwfix.
I'll be turning it off before I sleep... unlike the one at home.
Only an impeller with blades
