Which should you buy, Cooler Master MM731 or Ninjutso Sora V2?
Buy the Cooler Master MM731 for budget shoppers chasing sub-50g wireless weight and ambidextrous claw and fingertip grip users, though it is not built for buyers who dislike honeycomb/vented shells and palm grip users wanting a fuller shell. The Ninjutso Sora V2 suits weight-obsessed competitive FPS players and fingertip grip users wanting the lightest possible shell, though it is the wrong buy for players who want a mainstream brand's warranty support and palm grip users wanting a filled-out shell. 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 Ninjutso Sora V2 (8/10): an excellent choice for gram-counters, provided you're comfortable with a boutique brand's smaller support network.
