those logitec PC gamepads are so bad...I've had three in the past, and none of them lasted longer than 6 to 8 months. They all developed terrible ghosting with the left analogue, and the d-pad would often stop working altogether, and I was only using them to play NHL07 and NHL08 on PC. It's not like I was beating them up playing fighting games.
Maybe I just got unlucky a bunch of times, but I greatly prefer the madcatz pad, personally
