Corsair M65 PRO RGB Review @ Vortez
 

The M65 PRO RGB is now kitted out with a new Pixart PMW336x optical sensor (similar to the 3366 in the Logitech G900?), the same found in the Scimitar mouse. It has a resolution of up to 12,000 DPI and so we can expect a responsive, zero acceleration performance for increased precision. There is another change any Corsair fanboy would welcome. That is the return of the iconic Sails logo, replacing the fancy crossed cutlass design seen in our previous outing. ARRR! The logo forms one of three customisable lighting zones, with the forward projecting light and the profile/DPI lighting making up the other two zones.
