I'm waiting for tech support before deciding whether to return them. Can't get the music function to work. I bought 8 lamps and they are not connected. So if you turn on the music and try to make the light "dance", only one light will work, and if you change pages on your device, for example, go to your music app to play a different song that toggles lights completely off. I'm not sure yet. If I just wanted to buy "lights" I can get them at Home Depot for 2pm because of the brightness and multicolor. I wanted to try music tuning so I bought them. *Disappointed
