Very good value for its price, I have had it for almost 2 years and it still works perfectly. You might say that 2 years is not a long time, but I mention it because in the first year it had some issues, such as the humidity indicator sticking or the time being incorrect and needing frequent adjustments, etc. Its construction is not very high quality (it doesn't have a case to protect the screen), but it does its job decently. The color is a vibrant blue, although I rarely press it to see it at night. I currently have it in my room and I use it as a base for my dehumidifier.

I have 4 of these at home and they all have the same indications.
At most, they have a slight difference in degree.
The blue light is very convenient
