I bought the bulb based on some online reviews. The app gives an ok process of setting up the bulbs but it struggled to get a decent WiFi signal while the rest of my devices work fine all around the house. My main issue is that the app doesn't let me select the bulb to change colours or dim the bulb in any way. It seems the function to select the bulb just doesn't work. I'm not sure if this is what others have suggested and due to my phone running android 12 but that's a bit of a huge oversight
