The letters on the keys are not transparent so they are not easily distinguishable in the dark.
It does not change colors

It is a simple keyboard with illuminated keys. The lighting makes it look beautiful, although it is only one intensity and off. The key feel is mediocre. I would not recommend it for gaming at all. It is definitely worth it for 6 euros, but do not have high expectations. Those who are looking for a gaming keyboard, buy something else.

Generally, for around 5.5 euros, it is very good. It is quiet and its lighting is very soft so as not to strain the eyes. Yes, the build quality is not the best, but this also has to do with the user's behavior towards the material they have in their hands. One negative thing I noticed immediately is that it slides very easily on a desk surface, not that it moves during writing, but it is a point I wanted to mention. One last thing is that the button for the lighting is on the scroll lock, which will not be convenient at all for those who use Excel
