There are really only so many ways to innovate an input device like the mouse. However, the Rival 700 from SteelSeries found a way to solidly break through that wall, adding in some unexpected new features, like an onboard OLED display that streams in-game info directly to the mouse. This is also one of the only mice in the world with a haptic tactile feedback system that gives slight vibrations to notify you of in-game events or champion cooldowns.
Unfortunately, this mouse is a righty only. But other than that small little "hiccup", if you need something cutting edge to dominate in online gaming, it's well worth giving the Rival 700 a shot.
