Make sure you always have a controller charged and ready by picking up a spare. GameStop have them back on offer again, saving you at least £10 over the other sites. I've been loving the new controller since getting a PS4, the new triggers are fantastic and the analogue stick grips are vastly improved. Getting used to hitting the Share/Options button is taking a bit of getting used to, but I'll sync up over time. Battery life is reasonable, but plugging headphones into the controller or playing games that use the built-in speaker can drain it pretty quick. Charging time seems quicker than the DS3 though. Note: you don't get an extra micro USB charging cable with extra controllers.
