Although SteelSeries already has an iOS controller out on the market called the SteelSeries Free, it's out to improve and iterate on the design to introduce the Stratus.Like its predecessor, the Stratus is an incredible small controller compared to the other mobile controllers like the Samsung GamePad. Labeled as the first wireless controller for iOS 7 (sorry Android users) the Sratus is roughly the size of an iPhone 4S.Just right for GoldilocksEven with its diminutive size, the controller still feels beefy enough in our hands. The back is contoured with lines for our fingers to slip in and its overall shape is designed for grasping.Users with slightly larger hands will also be able to attach the plastic guard cover, normally on the front during travel, onto the back to make the controller feel more substantial.
