I gave this product a bad rating for several reasons. 1) One of the lamps I received keeps logging out and not being recognized in the app and needs a full read. (This bulb is in a cluster of 5 bulbs less than 10 feet from my router and the rest works fine in other rooms as well) Edit: after two days the other light goes out 2) The app for adding new lights is very annoying. You must enter the router password manually - token exchange is not possible and your credentials may be sent to other locations/countries. I don't have a PC and tools to check the traffic of this application, so I can't check it.3) The brightness change is small. Brightness 5% looks like it should be 20%.
