I give 2 stars for the application. First, because I installed them on the yard lights where the signal is marginal, if it is lost the program I have set up does not work. So they receive commands from the application instead of storing the command in the bulb. For example, I have set them to turn off every night at 12 and if the marginal one loses the signal, it does not turn off.
Second, the application is terrible and difficult to use compared to tp link's, which makes scheduling much easier and simpler. Here it is very complicated for something you want to set up simply and work. I bought them because they have more watts than tp link, but I will not buy them again because of this application and its functionality.

EDIT: While one bulb does not catch wifi signal, it now works with the schedule I have set up, so it's not a big deal that it loses the signal. The first day I tried it, it didn't turn on, but now I notice that even though it loses the signal again, it works on the correct schedule. I don't know if I did something wrong initially or if it just finds a signal and takes the commands, but in the morning I find them off and both (something that didn't happen the first 2 days) but they also turn on at night together.
Therefore, I increase the stars but not to 5 due to the application which I consider more difficult to use compared to the tp link equivalent where I also have bulbs.

Easy connection, very powerful light!
I have it at 80% in cool temperature and it's like daylight on the side of the living room where I installed it.
Attention, it requires a 2.4 network and not 5ghz.
I got it as a trial, but it seems like I will change all of them with the same brand.

It does what it promises and it's okay in terms of brightness. The application is okay, nothing extraordinary but it works.
