We bought a large number of these lamps for a project that did not go forward. Many of them we used in our homes and they are really very good. The scenarios are nice, you really change your mood depending on the lighting. They connected very easily with the app, although I plan to connect them with Home Assistant. A very nice feature if you don't have them in a smart hub is that with one press of the switch they become warm, while if you turn it off and on again it changes to daytime. So for the two basic functions, you don't even need switches, app, etc. It is easy even for the elderly to handle them.

Highly recommended!
