I bought this mouse for a reduced price of 12. The mouse can be quickly and easily installed by independent installation. The DPI number can be set as desired (slow or fast mouse cursor), which has the advantage that one does not have to constantly change this in the mouse options. This is beneficial for've shooter. The scroll wheel is rasterized and it can be easily scroll. Otherwise, the mouse works after a month yet. The only negative thing I have noticed so far, is the strange smell of rubber on the two mouse buttons. Both keys are coated with a thin layer of rubber and with longer use the fingers take part in these comic rubber smell. It reporting something wiederlig. After a few weeks but which is moved in any case. Otherwise, everything fits.
