It's just a bomb. Very bright illumination. There are drivers to do a change of illumination (although this can be done without a driver). The lower backlight is just aaaaa, it is impossible to look at. This is my first mechanical keyboard, so i can not say about the scroll. Also before the purchase there was no free delivery to russia, but thanks to the seller, he solved this problem. I advise people who love keyboard, especially with rgb♥️ Also included were tools for removing keycaps and a brush.
