In Dyson has obviously done a lot of good ideas and developed a fan that looks very stylish (would visually fit perfectly in Stanley Kubrick's 2001), evenly and produces air and thanks to intelligent technology while also still quiet.
The fan has 10 stages and supplies already at the first stage a good result. In step 10, the device is understandably a little louder, but still considerably quieter than fans with conventional rotor blades.
Even the annoying switching between the desired strength is not given here, the Dyson works remotely and still owns in addition a timer to switch off itself.
Conclusion: High-tech, visually very appealing, powerful and quiet. No bargain, but the quality in perfection.
