Absolute garbage. Everytime there's an update (as it seems), all my lights are disconnected from the WiFi leading to seizure inducing lighting effects, as in constant blinking. What is the advantage of buying Merkury/Geeni lights over illumeansent lights? Nothing, even from an I.T. standpoint. You will receive nothing but headaches and seizures, especially if this is how their updates work. You can change the color of the lights? WOW! But about the actual functionality that people care about? No
