When I received the mouse, I wanted to send them back only. Since the mouse looks cheap from the side and from below. But then I tried it on a laptop and, surprisingly, the mouse is reliable in operation. For me, a scroll wheel is necessary, that's good to control. Since the scroll single "Einraster" has, she turns as far as you want. The surface is non-slip, which also looks good. On the sides lights are housed, which gives the mouse a "gamer" look. As a surface you need a solid-color base, since the mouse is otherwise not go where you want Hinz own.
+ Scroll ok

Previously had a Tchibo mouse that was better. I liked the "back and forth buttons", but all in all it is slightly cheap. Prefer to invest more money.
Oh, and the button at the top center of the mouse has no effect on me
