Design top, power flopp

The unit is technically efficient a joke! 2 stars there for the beautiful design and the proven construction quality of the brand Vornado. That's about it. The Zippi is not only prohibitively expensive but also so inefficient that you no longer feel the air flow from a distance of 1 meter (at maximum fan speed). Below this distance, in turn, interferes with the low-leakage, direct air flow, at least for sensitive eyes and mucous membranes. Have oriented me to the positive reviews and was pretty disenchanted with delivery. Cooling effect is zero, the unit went back by return mail. Luckily problems because bought from Amazon.
PS From another Vornado, the 620 room fan, I'm absolutely thrilled the way for 5 years! A great device that keeps up of the cooling efficiency with good ceiling fans.
