Easy to install like any downlight. Out of the 6 I couldn't get 2 to work but they are easy to replace and everything is fine now. It seems that the electronics inside are very delicate, because. I put the bad heads on the workstations and they worked. The same, I put the working heads on the drivers in the problematic spot and they worked too. They just didn't want to work together. Easy to control from the application. A downside is that some colors don't fade very much - 1% pink, for example, is still vibrant. But in general I am satisfied with them, for the money I paid they work perfectly.
