Optical Gaming Mouse from Logitech is well protected shipped in a carton. A driver CD was not included, but is not also required. The mouse itself makes a robust and well kept impression. The Gaming Mouse features an optical sensor with 2500dpi. The mouse has a very low LOD (lift-off distance). When you lift the mouse slightly from the background, then the LED sensor over relatively quickly scanning. Some other mice, it may happen that unintentionally displaced or driven off during lifting and moving the mouse, the mouse pointer. In this mouse, this is not the case. The mouse comes easily cope with very many substrates. I use the mouse on a mousepad and aluminum could not notice any problems. Only glass mouse device quickly reach their limits. Who is working on a glass desk, must definitely use a mouse pad.
Overall, I am very satisfied with the optical mouse. The mouse is pretty darn good in the hand and the programmable buttons are within easy reach. It is ergonomically designed and well suited for larger hands. At the operation, appearance and processing can not be faulted.
