-New Omron Optical Hybrid Switches (Slightly heavier than Omron 20Ms and alot more tactile) It's feels really good for 1 tapping in game. It has a metallic pingy noise. -Same TTC Silver Encoder but the steps are less defined compared to the V1. It's smoother now and great if you have jump binded on your scroll wheel. -Slightly bigger battery now has 290mah compared to the V1 that has 240mah -USB Type C -Uses Nordic MCU paired with the new Hero 2 sensor that's now capable of going 2K hz (wireless only) -Very nice motion latency and click latency performance -Battery life at 2000hz polling rate is superb ( I been using mine for a bout a week now at 2000hz and I'm still at 66% battery life, compared to Razer 4K and other chinese mouse at 4K they only last for about 3 days) -Exact same matte coating that is grippy for people with moist and sweaty hands but it's slippery for people with dry hands. -Cleaning cloth

-Price (extremely expensive, I'd wait for it to go on sale unless money ain't the issue) - Accessories in the box are horrible, It has the exact same grip tape that offers no grip, and rubber cable USB type C -Side buttons are slightly improved but it's still mushy. Theres plenty of pre travel still but the post travel has been reduced. -Different bottom skates design but Logitech still using the old paper thin PTFE skates underneath -Useless power play feature (nobody really uses this)

It's a modern G Pro X Superlight. I believe Logitech might release a FW update in the near future to further improve the performance, perhaps a 4K FW update would be pretty nice. This mouse running at 2,000Hz polling rate is best paired with a 280hz+ monitor. I highly recommend the Zowie XL2566K for 1080p or the ASUS PG27AQN (both available from Memory Express) to go with this mouse.
