I have quite some experience concerning mouse types and I consider myself a intensive mouse user. I even paint a lot using only the mouse as input device. During the last year I used the Logitech MX518 mouse in the office and found it a really good, precise and reliable device. The form of the mouse is almost perfect for hours of painting and working with it. The ordinary mousebuttons and additional buttons are perfectly shaped and positioned. The mouse works very good on most surfaces and because of the fact that my old mouse at home broke down, it was an instant buy for me and I honestly can recommend this mouse! If you’re in need of a new mouse. Get it!
