Review on 4Pack 16.5W ECOELER 6In Dimmable LED Disk Light, 3000K Warm White - Low Profile Flush Mount Recessed Retrofit Ceiling Lights Fixture For Home Improved - Energy Star & ETL Listed Approved by David Carter

I am very pleased with this flush LED light once installed, so why 3 stars? It is is pretty tricky to spin the cover (or maybe I should call it the lens) on/off the unit which you need to do to get access to the mounting screws. I originally gave it 5 stars because the first four I could get the covers off/on with difficulty and when installed look fine and work great. Given that you rarely need to remove and replace the cover, I decided to leave it at 5 stars. However after installing 8 more, there was one I had to cut one of the three plastic tabs that hold the cover on to remove the cover. Believe me I tried everything I could before resorting to the Dremel. The remaining 2 tabs seem to hold it in place. Some of the others were nearly impossible to remove/replace but I managed without breaking. So I downgraded the rating to 3 stars because really these covers are much harder to remove/replace than is reasonable. Some are easier than others, so maybe there is a quality control problem?
