Firslty, I'd recommend wireless. But if its out of your budget then this pad is great.
The USB cable length is very long - some 3 metres so playing for most people is easy done.
The cable also has a detachment in it so if your kids run through and trip over the cable it will pull apart without pulling the console off the TV stand, the controller out of your hand or damage the USB port on the Xbox.
The size of the pad and rumble features are identical to the wireless controller, buttons are well based as are the anologue sticks.
Wanting a control pad for windows based gaming, then this is your man. Buttons are well placed, the size of the controller will fit most hands from kid to adult.
