Notwithstanding the attributes iPhone boasts off, an avid gamer may find it irritating to clench the gadget while in action. Just to answer this impasse, if it’s any, Trinity from Japan introduces the GameGrip for iPhone. The accessory touts a silicon sweat-proof coating to ensure it doesn’t slip off your hands. You can summarize the time in the rear and there’s a Home button on the right. Also, a slot for cables is there for those who prefer playing with the headphones on. The dimensions read 158 × 147 × 38mm (W × H × D) and it weighs around 175g only. Not to miss, you can charge it while you go live! Available here for 4,980 Yens, for Japanese customers only.
