The RGB effects are bright, well lit without being too distracting, and has multiple customizable features for illumination

Compared to the K552 Kumara, this keyboard felt lighter, and a little less robust

Color schemes (moving / changing back light) were initially unnerving, but actually seems to encourage work.

The back lighting is fun, but it's the mechanical aspect of the board that I love.

Sound is pleasing and the lighting is great.

There is no outside software that I needed to put on my computer and the keyboard has 18 different light patterns ready to go out of the box.

There’s no need to spend $80+ dollars on a tournament keyboard when the K561 gives you not only the performance but also the fancy light show
