An absolute top fan. Very effective and very quiet. The design and the quality of all components are very good. I wanted a Dyson fan (299 .--) Buy for its futuristic design and also because it is relatively quiet. Then I luckily this Rowenta VU 5540 discovered and tried out. Result: even quieter than the Dyson, air power much stronger and in an equally futuristic design and a price of only 70 .-- As much choice really was not difficult. Clear Best Buy with 5 Star ++ !! Who wants to experience about wind force 6-7 in the living room should buy this part absolutely. However, if at level 1 only a gentle breeze wants this top device should not buy.
