"Logitech continues to expand its G series of gaming products with G9, the latest super gaming mouse for hardcore gamers. The company nails the design once again with a black, mystic exterior, and an interesting design with a host of programmable buttons. With Logitech, customization is where it's at, and surely the G9 is no different in that regard. In addition to the programmable buttons, you can also customize the on board LED lights to work with specific profiles. For instance, with Logitech's Setpoint 5.0 application, you can set up to 5x profiles, and all of these profiles can be programmed to display different colors to alert you, the user, about their status."
