So this threads off from the other topic I made about this mouse. I found out more about this and apparently if you buy this mouse you get a free cd copy of the Ultra Core 3 upgrade unless the seller takes it out. Ultra core 3 upgrade allows you to have no recoil and no spread completely undetected. I think you can somehow get it for free but I don't know as it updates often. The "hack" works for any fps literally.
