It's not often that PC gaming tech takes a huge stride these days. So honed is what we already have that truly groundbreaking ideas are hard to come by. When it comes to gaming mice, over the past 20 years we've only really seen two huge changes. The first was the return to optical sensors, after the misadventure that was laser sensors, and then came the arrival of really good, low-latency wireless. With the launch of the Logitech G Pro X2 Superstrike, though, we can add a third item to that list: HITS. Haptic Inductive Trigger System is the core technology at the center of this new mouse, and it completely replaces the conventional switches of the left and right buttons with inductive sensors and haptic feedback actuators, making for a mouse whose clicks can be tuned to precisely respond just how you like. Not only does HITS allow for altering the trigger point and haptic feedback of the button, but it also unlocks a massive step forward in the potential response time and overall click speed of gaming mice, plus it allows for Rapid Trigger. It alone is not enough to make Logitech's latest the single best gaming mouse on the market for all gamers, but it can revolutionize certain uses, and feels like a glimpse of the future. In fact, it's so different from the norm that I've taken longer than usual to review this mouse, in order to truly get a sense of where it does and doesn't deliver on its revolutionary promise. Four weeks in, I've fully made up my mind. [site_jumplinks]
