11 of 12 bulbs were very easy to bring online and can be added to the same room as others with no problem. The 12th bulb is completely rogue and cannot be added to a room on the app. It happens to be the hardest bulb to reach in the whole house, so I'm not about to actually do anything to fix this, but it does mean that we can't turn off all the dining room lights with a single request.
As far as light output, they're fantastic. I like how easily I can turn all the lights to the same temperature, color, and brightness and that it remembers the setting. Except as noted above, they have been really easy to control with both the Daybetter app and Alexa. It's also nice for nightlights and having less harsh white lights in the evenings.
