Logitech MX Master 4 vs Razer DeathAdder V4 Pro

Buy the MX Master 4 for office work, long editing sessions and multi-device switching; buy the DeathAdder V4 Pro for competitive gaming and fast, low-weight aiming. The MX Master 4 wins on comfort, button count, the MagSpeed wheel and haptic feedback, and owners consistently praise its ergonomics and battery life, though some find it heavy and awkward in small hands. The DeathAdder V4 Pro wins on weight, sensor ceiling, polling rate and optical switches, but it has fewer buttons, no free-spin wheel and a much thinner review base.

  • Choose the MX Master 4 if you work at a desk all day, juggle several devices, and want a large comfortable mouse with a free-spinning wheel and plenty of shortcuts.
  • Choose the DeathAdder V4 Pro if you play fast-paced games and want a light, low-latency mouse with a top-tier sensor and optical switches.
