The damn thing doesn't work in any Windows prior to Windows 10. While the ABXY keys are springy enough to increase speed, they negate that benefit because they're big and sticky, which ins Game comes way finger movement. However, the analog sticks are lower on the body and don't twitch thumbs, which is an advantage over all generations of the Xbox One controller. The D-Pad, while fast, is too jittery for fighting games. In addition, it is a durable and fast controller. It's sad I couldn't test it because Windows doesn't recognize it. FU Razer! I refuse to switch to this bloated mess called Windows 10.
