I am satisfied with the product. I think the fine dust measurement sensor is broken. Even if I put it on the window when the fine dust is bad, it only shows blue haha. Buy Xiaomi.

It's a very bright color, so it's neat and pretty. The price is cheap and it's the perfect size to keep in the room. It's easy to operate, quiet, and you can tell the air quality by the color, so it's convenient to use. ^^

It's quiet so it doesn't bother me too much. It's a touch that doesn't feel like you're pressing a button. It's white, light, and clean.
