Query: Failed to deliver performance.

Picked this up for better success with fighting games, and it is completely nonfunctional by any degree of expectations. It doesn't read inputs clearly at all, and requires you to smash the buttons for any sort of input. It does not read diagonal inputs practically at all, and for anybody who is a high-end player, it can be deemed complete trash.I'm in the process of sending it back now, as it utterly failed to meet my expectations of smooth responsiveness.
