Pro Compact size gaming mouse
People with small hands needn't look at mice like the Corsair M65 gaming mouse and despair. The G303 gaming mouse has a solution. It's about the size of the $5 USB mice that are often bundled with desktop computers, but it has most of the features of a full-size gaming mouse.

Con Always wired
Not a pleasure to use compared to wireless.
Con DPI manual switching button placement is poor
The placement of the manual DPI "on the fly" button could cause users to accidently swithc when actually trying to use the left mouse button.
Con No longer in production
Discontinued and there is no direct replacement.
