Who each one is for
The Cooler Master MM731 suits budget shoppers chasing sub-50g wireless weight and ambidextrous claw and fingertip grip users, though it is the wrong buy for buyers who dislike honeycomb/vented shells and palm grip users wanting a fuller shell. The Logitech G703 Lightspeed is the one to take for shooter and MOBA players who value proven Lightspeed latency, though it is not the pick for players chasing sub-70g ultralight weight and ambidextrous or left-handed users. It also earns its place with palm and relaxed claw grip players who want a filled-in ergonomic shape. It is the wrong buy for buyers who want the newest sensor generation at this price point. Our rating of the Cooler Master MM731 (8/10): one of the best value-for-weight wireless mice available; it just lacks the sensor polish of pricier flagships. Our rating of the Logitech G703 Lightspeed (8/10): A comfortable, reliable wireless mouse for players who want an ergonomic shape and don't obsess over shaving every last gram.
