I've had these for about a month. The colors are great, and I have really been enjoying setting a wake up time to turn them on. However, the app has been buggy and inconsistent. I'm frustrated in particular with the labs function, which for some reason doesn't seem integrated into the app itself. Sometimes the labs settings interfere with my use of other settings, changing color temperature and light levels willy nilly. It is a pain to have to open the app, navigate through multiple screens, open labs in an in-app browser, and sometimes even sign in again to change one or two interfering settings. I hope these bulbs last as long as they claim to, and that the app and controls continue to be developed.
