These have great features, but one of my brand new bulbs stopped working entirely within 3 weeks of moderate use. Connected to the same lighting fixture as the 3 other included bulbs, one suddenly became unresponsive on the mobile app and does not turn on to the default mode, or at all, when giving the bulb power.
