Mice looked a little cheap at first, at the same time it is normal, it is "cheap" ... Parameterization software download very intuitive, 3 sensitivity settings to choose between 400/800/1200 etc ... up to 3200 dpi, settings buttons also include different "clicks" of the dial. The mouse is relatively big guy, not recommended for small hands. To see in time for reliability but nothing bad at the moment, very good price / quality!
