I bought these for my husband when they first came out. At first I was hesitant in purchasing them because of the price of the unit, plus the price of each individual bulbs... getting to the point, our whole house is now outfitted with this system. The app is extremely user friendly, allowing you to Customize your scenes to suit the mood. It allows you to dim, or turn on and off lights in rooms your not in. (Forgot to turn your bedroom light off? You can do it from your kitchen.) The game changer for us was the cost savings with outfitting your house with LED lights. It's incredible! I highly recommend, and if you do not want to invest in the hue, invest in Philips LED lights. Save money and the planet!
