Excerpt: It’s difficult to improve on something that’s already damn near perfect. That’s the problem Logitech faced when designing the follow-up to the kick-ass G5 gaming mouse. The new G9 features an innovative, but not necessarily improved, design. Sporting changeable shells, the mouse accommodates all hand sizes. The petite “ladyhands” shell is perfect for people with finer fingers, while the “meathooks” shell is big enough to accommodate everyone but the largest of giants.
Pros: Same precise sensor as the G5; adjustable weight system; haptic scroll wheel.
Cons: Designed for claw-grip gamers; uncomfortable for day-to-day use.
