The device has two major drawbacks:
1) The cable is clearly too short! This handicap can resolve even with an extension at a pinch.
2.) The rotor runs strikingly out of true and puts the complete fan shell to vibrate. The strong imbalance is to be feared that the bearing of the motor shaft wear prematurely and as a result, the volume increases significantly over time. In a 80 euro fan should not happen like that. Ultimately, this lack was the determining factor for the return. Without this problem you could certainly have awarded 4 stars. Pity!
