4 light bulbs were purchased for the living room instead of installing Sonoff switches that I was considering. The connection with the Yeelight app was very easy. They were immediately connected with Google Home, but this lasted for 1 week, then they disappeared from the Google Home app and voice activation/deactivation was not possible, which is why I bought them.. The only thing I managed to do was to enter the Samsung SmartThings app and synchronize the Yeelight app there, so they appeared again on Google Home. The negative is that they all turn on and off together.

Very nice lighting. Satisfactory and relaxing in terms of intensity and color. The only problem I found is that I installed five spotlights that are controlled by one switch, and through the application, I have to "connect" them one by one in order to manage them and (if I understood correctly) then group them. At the moment, I find it very time-consuming, so I only use the switch. Once I connect them in the application, I will come back.

Very good lamp and worth its money. I remove one star because although it claims to be compatible with Apple HomeKit, unfortunately it is not. The Yeelight bulbs appear normally in the Home app, but not the GU10 ones because such a connection does not exist in China. It appears normally in the Yeelight native app, as well as in the MiHome app.

Easy and direct connection with the Mi Home (or Yeelight) app. I connected 6 spots and you can group them and behave as one (although losing some functions).
Lighting at 100% is quite powerful for spotlights and is fully adjustable through the app.
The color is warm white, there is no option to change the temperature.
The only negative is that the body of the spot is made of some kind of plastic and I don't know how it will behave with temperatures.
Overall satisfied with the result.
*3 years later, the bulbs continue to perform exceptionally! No issues with temperatures, etc...
