Hi Conkir
Welcome to the ROG forum.
The ROG Chakram X is available to purchase at your favorite online stores.
I'm using the ROG Chakram X and I think you'll be happy with the switches it comes with, I don't know if they are optical switches, it just says micro switches in the specs.
It even comes with an extra pair of micro switches.
RGB is controlled with the Armoury Crate software.
Here's what you get in the box, the mouse and a big long list of accessories.
