Cons


Con Somewhat heavy
Being that this is a wireless mouse there is the battery weight to contend with. Batteries in the weight of the device is 152 grams, which isn't all that bad considering but still not for users that like a lighter mouse.
The mouse can also be used with a single battery, which is useful for not only reducing weight but also for balancing the mouse. With two batteries the mouse can be a bit slipper on the right side when picking it up as the pinkie and ring fingers don't have as much to grip - but balancing the weight over towards the thumb allows the mice to be more easily picked up as the side buttons allow for a decent place to grip.
Con No wired option
The Logitech G602 does not offer a wired USB option, only wireless.

Con Macro Key Defect
Side buttons are known to register multiple keystrokes occasionally when pressed only once. With bindings such as Ctrl+F4, this naturally has destructive results.

Con Middle mouse button wore out after a year of heavy use
And with no way to open it it's near impossible to fix.
Con Scroll wheel
Although it features nice, defined scroll steps, the rubber coating on the X5's scroll wheel is quite unexceptional to say the least.
