The installation instructions are pictographic, so OK if you are an IKEA fan. Some parts are already assembled, which is a bit confusing. The screws that hold the ceiling shroud in place need to be unscrewed from the fitting before the shroud can be fitted. It is quiet. I had an AC fan before and it whined like an abandoned puppy. This DC fan is silent even on higher settings except for the sound of the air moving, which is constant and subliminal. The loud beep sound on every input from the remote has been mentioned in earlier posts. Based on this I removed the sounder from the PCB - a simple job but be aware there is an on the board resistor directly below the sounder, which you don't want to damage. The colour temperature of the light can be set from the remote so it always comes on at that setting. The dimmer works by pressing and holding the + or - button. At the 2 setting (of 6) there is a pleasant cooling breeze. 6 would probably induce hypothermia. The reverse button seems to do nothing but the fan gently slows, hesitates and then reverses direction. Overall this is an excellent ceiling fan.
