Razer DeathAdder V3 Pro

The DeathAdder shape has been the most copied ergonomic gaming mouse for over a decade, and the V3 Pro refines it to 63 grams while keeping the supportive right-handed contour. The optical sensor and switches are top tier, and the wireless connection is genuinely lag-free. There is no RGB lighting at all, which is a deliberate weight saving. Battery lasts about ninety hours. If the shape suits your hand, this is close to the reference competitive mouse.
