Very useful for charging any of the Move controllers without the need to keep the PS3 on. Works with any of the two controller types - motion or navigation, in any combination (you may use it to charge one of each, or two of the same type, or just one).
I would have liked, though, the charger to be fitted with a switch or something such that I could use the charger just as a support to keep the controllers neatly placed, without charging them when the bateery is only slightly discharged. Also, one or two USB ports to enable charging the regular controllers in the same time would have been really useful. Otherwise, it's a good quality product, with nice glossy finish. Does the job as advertised and looks good on the TV stand or by the PS3.
