I had a Logitech MX518, almost the same design but much older. And age at the G500S offered a superb sensor, juicy texture, a DPI indicator in addition to the buttons and to change the wheel much more comfortable with the possibility of change in infinite scroll mode (without detent) for scrolling more long and fluid. The cable is now braided it for a "premium" effect.
The software for the program is still perfect.
Point disturbing for some: the acute sound is present at rest, most can not hear myself as a teenager I can perceive the adults but you will not have any problems.
