As part of those improvements, we see the PixArt PMW3366 optical sensor, which is widely regarded as the world’s most advanced optical sensor. LIGHTSPEED connectivity comes as standard, offering lag-free, wireless, 1000Hz transmission to the PC. We also get PowerPlay compatibility, Logitech’s wireless charging technology. Last, but most certainly not least, is the RGB lighting added to the top and scroll wheel.
