First of all I would like to say that this is a good complement to the Logitech G products. I currently have G502, G502 Lightspeed, G910 keyboard, G933 headset and a Powerplay mouse pad. The only reason I'm giving this one star is because programming the mouse requires a software download. I have a damn good computer but when I open the software my CPU is at 99% usage, everything in the program is unresponsive and it will just make you angry. If G-Hub stays, I will never use Logitech accessories again. If they can get G-Hub to stop pulling their hair out I would give it 5 stars.
