Easy to use. Screw in the lightbulb. Take the supplied remote control and remove the plastic label from the battery terminals, then select the color/effect on the remote control. No issues or issues connecting to WiFi! This remote control is everything you need for flawless remote control access. Maybe it's the best after sliced bread! Seriously, it even allows for 3 brightness/dimming options. Your light doesn't even need to have a dimmable switch. My only wish is more wattage but I plan to buy more of these and will buy different watts for different lights and rooms. It far exceeded my expectations!
