I gotta say, Dimitri is wrong about sponsors in CS. They are not forced to use their sponsors gear, that´s why Niko is always swapping between Zowie, Logitech, Vaxee and now Razer mice. Jks also used a Ducky during his first months at G2, Teses uses a non Xtrfy Keyboard, and NAF uses a Custom Keyboard even tho they´re sponsored by HyperX. It´s simply that Pros, specially in CS, don´t care as much about Keyboards so they utilize whatever they are given, it´s also easier to get access to new gear when you´re sponsored.
