One problem, the battery case. Its smack bang where you rest your fingers on the underside of the controller. It changes how you put your fingers on it and at first i thought it wasnt all bad but then, after a month or two of using i just coudont stand it anymore, i actually begged my 10 year old cousin to let me borrow/keep his SONY ps2 analogue dualshock 2 controller and have never looked back
