Canada>Canada an essay on college life After using SHIELD for about a month, it’s clear to me that NVIDIA spent an exhaustive amount of time and energy creating what they considered to be the perfect mobile controller. There is no compromise here: SHIELD is huge, even when compared to game controllers alone, and every millimeter of the hardware is meant to make extended play sessions comfortable and enjoyable. Take a look at the bottom of the case. See that groove that runs about halfway between the triggers and the beefy contours where your palms sit? That is a resting place specifically made for your middle fingers. There’s nothing else to say here: SHIELD has no equal when it comes to gaming controls on a mobile device.
