Logitech G400 Optical Gaming Mouse

• Rock-solid performance for when your sights are set on victory.
  If you liked the Logitech MX518, you'll love the G400. You get the features you've come to rely on with improvements in precision and speed.
• Precisely right
  When an ordinary mouse just won’t do—a 3600 dpi optical engine, 2X greater dpi than the MX518, gives you precision targeting and pinpoint accuracy.
• Stay on Target
  Instant access to four dpi levels lets you shift from pixel-precise targeting to lightning-fast maneuvers.
• Battle-tested
  A sculpted comfort grip, low-friction feet and eight programmable buttons keep you comfortable and in command.
