Logitech G502 Proteus Spectrum Optical Gaming Mouse: With 11 programmable buttons, tunable weight, DPI switching and customizable lighting, this mouse offers the ultimate in personalization. High-definition optical technology adds a reliable weapon to your gaming arsenal.
Any review of the quality and performance of the G502 Proteus Core will apply to this mouse as it is simply the same mouse with no blue plastic and the addition of RGB lighting.
I tried other gaming mice at this price point and just couldn't do without the flick-scroll functionality of the Logitech scroll wheel. I'd grown accustomed to my old Logitech G9 and this mouse matches or improves upon every aspect of that mouse.
The Logitech Gaming Software, that manages the button, sensitivity, and color profiles, is lightweight and easy to use (only uses about 30KB of memory to run in the background).
If you don't care about matching color with your other components or keyboard, then stick with the Proteus Core. Otherwise, I highly recommend this mouse for top-notch performance, comfort, and aesthetics.
