Overall, the Logitech MX518 is an excellent mouse. It's powerful, fully functional, and smoothly glides across surfaces with one of the highest dpi settings on the market, and feels great while doing so. Its buttons are easily accessible and well-placed, but not in the way, and fully customizable to boot. Pressing down on the middle mouse was my only problem with this mouse, as it has firm resistance to depressing it, but it solved itself over time. While this can be annoying at worst, it doesn't change the fact that this is one of the best mice I've ever used, and at such a low price, it is one of the best valued mice I've ever used as well. However, if you're a lefty, or prefer the wireless breed, this mouse is not for you. If you are right-handed and don't want to deal with the problems that arise from wireless mice (batteries, delayed signal, high cost) then this mouse is definitely worth a try.

The MX518 is a highly responsive mouse that's fast, but offers a substantial degree of user control and configuration. It's a worth contender for best gaming mouse.
