After years of searching and testing of tens of mobile notebook mice I am first time remained in this - for mobile use. The sensor is first class, the pointer responds quickly, precisely and, above all, he goes straight, uniform and jerk (el) freely across the screen when you move the mouse as well. Using the buttons you could sometimes quarrel, pressure especially when the right button is way too soft, as it helps fortunately the finger next to the wheel lay on the bar if you do not always want to inadvertently open the context menu. The driver, however, is a mess. Mouse wheel and lateral scroll function work in some programs only with drivers, in other programs only without loaded drivers if they work at all correct. Regarding settings and configuration of the mouse in the driver Ebbe is hip - since it is almost exclusively dependent on the mouse properties in the Control Panel.
