I have the cool air fan now for about 3 weeks and after the 3rd time felt turning now flew me all the parts around the ears, and I had to gather together the fan at the bottom. Completely secured now with scotch tape, so far back fully applicable - at least until the battery change.
The fan is also but a bit noisy (contrary to other reviews).
Standing, as in the picture as a "desk fan", actually does not work as a result of the air flow of the head is pushed back.
Another positive is the pleasant airflow. Because you can not say anything, he cools :)
Conclusion:
I would buy him no longer the next time it gets back the 5 Euro-blower from the supermarket!
