I have to tell you, read the instruction for assembly couple times, and then spend time to look at the parts, so you know what you are doing ... the worst thing about this fan is the assembly manual ! A great product with a poor manual ! When assembled this fan and light is great ... it took me 2.5 hours for the first one and about 1.5 for the second ... some how one of the controller unit lost connection with remote control, had to spend time to figure out what was going on, but you can reset the control and controller and them again .... overall looks great, works great and good quality ... love it so far.
