Normally it's only with the usb cable as far as I remember, for info it's really a cheap thing, it's fragile and really not crazy if you want pallets there's much better out there
Probably not. Since the knitted pack encloses the controller in the middle of the PS button, it won't work with a grip skin. Unless you cut your Gripskin out in the middle. I would definitely recommend this product! More than just awesome, it makes you a much better player once you get the hang of it (but takes time and practice).
