Logitech’s G502 Proteus Core Tunable Gaming Mouse flew under our radar when it started hitting shelves in April, but this mouse has features and the price tag to make it worth your attention.
The marquee spec here is the DPI range of 200-12,000, adjustable on the fly. New ergonomics, aesthetics, and custom weight, surface calibration, and balance are all notable features here as well, especially on an $80 mouse. There are five easily movable and removable weights, and 11 customizable buttons, along with the classic Logitech dual-mode scroll wheel. Mechanical microswitches and a braided cable are also nice touches.
