I have not had the same problem as the previous review, the hinges work fine, mine doesn't feel weak like it would and overall i cant complain. It exactly what i expected. It made out of plastic and metal and feels sturdy. It can accommodate two ps3 controllers. My main I purchased this product was to be able to charge my controllers through mains power while i was out so that my controllers are always fully powered, rather then leaving my ps3 on to charge my controllers. Also has helpful led indicators which show when controllers are charging or are fully charged.
I could not find one fault with the ammo charging box, and would defiantly recommend.
