Well since you were thinking of getting one let me explain a little more about why I sent to it back.
The triggers don't have springs in them like the 360, they work with magnets. This takes away the resistance and feeling you get - and probably have never thought about - with the 360 controller. The triggers were just far to light, don't get me wrong, it's probably a fantastic controller for FPS games but for feathering a throttle it's disgusting.
The sticks, well I'm not bragging but I think my nipples have more surface area than they do
