- The device is a permanent "clacking" of itself, which varies in volume depending on the stage.
- The ratio of blown air flow volume and is unacceptable
- Even the highest level is only a gentle breeze
- It smells slightly burnt plastic over time
That with the instability I can not confirm, I am sometimes full thundered against it and he is indeed back and forth staggered but did not fall. Mag but be that there are more stable contemporaries.
All in all, I have to revise the positive reviews. The device is absolutely not recommended. Even at the price one would have expected more.
