No idea about corsair. I have never used it nor do i know anyone who has used it. My advice to you would be to stick with logitech, roccat, steelsries and razer for gaming mouse. Another buggy thing about these gaming grade laser mouse is that if there is even a little bit of dust on its sensor or on ur pad there is a high chance that your mouse won't track properly. Laser mouse works best with a hard pad. Soft pads can also be used if they are cleaned properly.
I had qck heavy and it worked well for like 2-3 months with my steelseries xai. But as soon as it got a little dirty my mouse went haywire. Finally i had to buy a hard pad(Razer Scarab). Thats just my personal experience it may not be the same for everyone. But in my view optical mouse are more reliable.
