Easy installation if you have the correct size hole saw (6.25 inch). Quick connectors instead of nuts, but that's not so bad. Other brands have a quick connector. I've installed over 40 of these and they work well, look good and have lots of light. I recommend the Essentials line instead of Basic li e if you want more light. I chose the 3K color (not adjustable) and we love it. Would buy them again.
