The mouse is enough wide, but not too long, which makes it a little difficult to use for users with bigger hands. We did initially try the mouse on our 27’’ 2560x1440 display and the preset resolution of 1000 DPI was not enough but as soon as we did switch to a FHD laptop display, Gentix Silent has performed quite fine. The product is plug-and-play and does not require any additional software to function.
