The "Rainbow Storm" (whoever those product names comes up with anyway?) Came on a rainy, cold day in July with me. No suitable test conditions, unless I interest of pneumonia would have. But the summer was still and I was able to test the little ones a week camping in the Greater tent. This was also urgently needed, because at some 36 degrees Celsius outside temperature and no wind it was about life and death. So almost. The Püster ran some ten hours a piece, even at night. He was knocked down numerous times by mistake, the tilt angle was changed 100 times and also the intensity of the rotary switch constantly changed. What can I say. He has come through everything without complaint, made a lot of wind and was so quiet that you could sleep. The engine is barely audible, only the wind noise rushes through the Heat of the Night. The airflow is pleasant, not as with other models, where it is believed to sit in front of a Kaltluftföhn who blows a frostbite on his body. Delivering an area of ten square meters, making it to ventilate well, so he can do more than just pass for a paper pusher. The design is appealing, the blue-violet coloring modern and not too squeaky. Operation is simple, the device was made and the performance is very good in all three stages.
Conclusion: To complain there is nothing and for the offer price can not go wrong. The EIA I find somewhat exaggerated.
