The bulb constantly disconnects and the app breaks (it says the bulb is connected but I'm unable to change any of the colour settings or brightness). I sent in a video of the app being unresponsive to their team, and they came back telling me it was a wifi issue (it isn't - the bulb connects. I can set my wifi to 2.4ghz to allow for it). I don't like leaving bad reviews, but the lack of help from their team sealed it. Avoid this one.
