Since its release back in mid-2014, the Logitech G502 Proteus Core has found itself permanently attached to my gaming rig. It convinced me to leave behind the trusty Performance MX wireless mouse I'd used for years and go back to the cord, though the dream would be to own a mouse as responsive as the G502 without a wire attached. That dream has now been realized with the new G900 Chaos Spectrum. Logitech has redesigned the G900 from the ground up to not just be a great wireless gaming mouse, but rather the best gaming mouse money can buy period. At $150, the G900 costs about twice as much as you might typically spend on a gaming mouse, but Logitech assure us that it's worth every cent. The G900 Chaos Spectrum puts an emphasis on weight, reducing it as much as possible. Every aspect has been scrutinized to remove fractions of grams, from the thin wall molding to the hollow "spoked" hyper-fast scroll wheel design. The result is a wireless gaming mouse that weighs just 107g, which should make it comfortable to use over long periods while delivering quicker response to motion. Read the complete review.
