I bought 2 bulbs and grouped them for the same programming to work on both. They work great as advertised. All supported features work for me. And the 2 bulbs stay perfectly in sync. But there are some features that I was expecting but found VERY disappointing: 1) There is no way to choose colors other than the color wheel. So if you're picky, your RGB is 255255.0, not 2542551, you'll spend many frustrated minutes placing your finger directly on the color wheel and very carefully lifting your finger right off the screen. 2) Sunset and sunrise force you to use white. There's no way around it. They may not have a single color, no color fading. A beautiful orange-red sunset is not allowed! 3) Transitions only allow you to adjust color or brightness, not both. 4) Timers cannot use your custom transitions. 5) Timers do not have a fade option. When a new timer is triggered, it immediately jumps to the new setting. I discovered #3, #4, #5 trying to find a way around #2 because #2 was what I wanted to use the lightbulb for. I plan to buy 2 more bulbs when they add features that will allow me to create a colorful sunrise and sunset. I plan on returning the 2 I have if they don't. On the other hand, 2 complaints I see in many reviews turned out to be myths. 1) It's a myth that you need to have your mobile device within Bluetooth range for this to work. As long as you leave the lamp on and only ever turn the lamp off by programming, the lamp will follow its program without your mobile device being nearby. 2) The control app receives many negative reviews in the Google Play Store. because it takes so many permissions. Many make the false accusation that the app does not require permissions. The truth is that the app actually has a function for every required permission.
