The delivery took place two days after Amazon typical order in one handy package. The installation manual is quite extensive, because it is written in different languages, but the installation is not a problem, and also to cope alone without problems. However, the connecting cable that comes out of the ceiling should be as not still in its main insulation, but consist only of the three individual cables, otherwise the space is not enough to the receiver nor accommodate, I had to rework only with me. Like most here, I also have stronger screws for mounting used in the reinforced concrete ceiling. The only mistake I made, I have the 4-way connector interchanged during assembly, because I could not see clearly for the life of the instructions which belong together. I had then decided to put the two plugs that were marked with a red arrow along what was wrong. Mind you, I have of course only when I had installed everything and wanted to make the trial run: The fan immediately went to Stage 3, the remote does not respond and the light was not dimmable. So again the blades off the cap solved the cable reconnected and reassembled everything still took me half an hour. My tip: press When assembling after plugging the cable just once briefly the light switch on the wall, then the motor should rotate, the wiring is reversed. He remains calm, everything is okay. Subsequently, everything worked as it should be. The fan is at level 1 absolutely inaudible to me and runs smoothly, at level 2 and 3 is only a slight imbalance exists, which I did not get away well by reversing the fan blades. When listening at times also quietly clack noises by commuting to the suspension, but I will still try to get the balance with a 5g-rim adhesive weight from the car area under control. The built-in light is super-light for only 80W and is dimming down to dark ambient light. The fan looks elegant and impressive in terms of size, stage 1 produces a gentle stream of air, which is perfectly suited to sleep, stage 3 could power an aircraft ;-)
Because of the drawbacks with the imbalance I give 4 stars, otherwise I would have awarded full marks!
Update to unbalance elimination: I got now balanced the fan by a 5g-adhesive weight of the car tire assembly, so except for the sound of escaping air now at all levels no longer be heard and the body no longer commutes. I'm going proceed as follows: select a wing and fix this by starting the weight provisionally sequentially on all wings approximately in the middle and thereafter make a trial run. Now watch carefully whether commuting rather strengthened or weakened (or rather the sounds Doller or less). When you have the wing with the best running properties found, you have to try this more different positions of the weight of a test run, so rather the fulcrum, or outward. When you have found the perfect attachment point, the weight attach final (the weights are self-adhesive) and look forward to a smooth-running ceiling fan ;-))
