2 good idea shame their not practiclebrownievec | 28/12/2010 | See all brownievec's reviews (4)bought the red and blue set for my two girls with two controllers and two navigation , two guns (different types) and a quad charger.with the controllers you already have the official wrist strap. so thinking this would offer a nice cosmetic touch and help them differenciate whose was whose. i found one fatal flaw other than if you want to charge your controllers with skins on then you can only use the usb cable and leave them charging via ps3 and lying down. as these are licence by ps3 with their logo on the strap i thought sony would have shared some practical hints with the product design. same with any sleave from anyone else for your move controllers as the design flaw is as follows.......with skins on , they do not fit any charger or any gun as the skin makes the controller too thick and you have to strip them naked, pain ,kept the straps on as they are colour coded now with red and blue but put the skins safely away , probably never to be used , .
