Our kids had the wired version of those controllers - they did not last very long before a couple of the buttons stopped functioning on one and the fan supplying the airflow died on another. You can replace them with computer cooling fans (40mm i think) but it must have been a faulty connection as the replacement petered out quickly as well. Their brief interest in xbox seems to always get overshadowed by their computers once they try to play any sort of FPS with the controllers (as oppoesed to kb/mouse).
