Renegade Reviews
"Overall, I find the Logitech G502 to be one of the most comfortable and easiest mouse peripherals I've ever had the opportunity to work with. From my corporate daily life right through to my alter-ego buried within long gaming sessions, the G502 is loaded with great features out-of-the-box and even more customization available with the light and efficient G Series Software. I seriously love this mouse and all it stands for." Full review
