Basic set of wireless keyboard and mouse. Highlighting the innovative V-Track technology – thanks to the enhanced beam that penetrates deep into the structure of the surface, the mouse operates smoothly and precisely on any 3D surface such as fabric, glass tables, marble floors, etc. The 2.0 optics have arrived – in this situation, the pad becomes unnecessary! The 2.4 GHz wireless technology provides a working range of up to 15 meters and an energy-efficient battery system (more than half a year with a single AA battery). The set comes with a mini-nano receiver that is hidden in the bottom of the mouse housing for easy transport. A distinctive novelty is the elimination of typical functional disruptions and delays in the wireless transmission of cordless mice. Included is the multi-nano receiver that supports all G7 and G9 series of A4Tech wireless products – there is no need to use multiple receivers simultaneously; it is sufficient to calibrate all devices with the software provided by A4Tech.
