Pros: Ease of use (grouping into rooms), many modes, colors, etc. With its cons: It lasts for a couple of years, then some start to blink on their own, change colors, some do not turn on a certain color, but this is probably normal for such a service life, I use them as the main lighting every day
To help provide a better understanding, I've attached some photos.
