Summary: The S in S 510 stands for Style and Simplicity. This is true as this product offers very few extra features. Its stylish, simple design is a perfect match for a large LCD monitor located on your desk. The polished-black and dark-silver color scheme is in line with today’s PC. Only major complaint is the mouse and its design. Other then that, Logitech managed once again to create a superb mouse/keyboard set.
