I had a friend help with the installation because he they had experience with installing such things.  It went quite smoothly, though the length of the wires made it a little challenging, as they only just fit inside the unit if packed very tightly.  It took a few tries.  It's well-enough made for the price and the fan is practically silent on the lowest setting, which is great for overnight. It's a bit frustrating that you have to use the remote to cycle through each type of light (very bright cold light, slightly less but still very bright cool light, and finally a slightly softer, warmer light that is still on the bright side) to get to the one you want.  I'd rather it could default to my preferred light.
