Chinese company ORICO unveiled the KM6116 value wireless keyboard mouse combo, that includes a 1600 DPI 3+scroll button mouse, and a narrow QWERTY keyboard with the EN-US keyset. The mouse uses an optical sensor with resolution switchable between 1600, 1200, 800, and 400 DPI, on the fly. Lower resolutions could help conserve battery. In its belly, the mouse hides the battery compartment (two AAA-size), and a space where the 2.4 GHz band wireless USB micro-receiver can be stored for transportation. The same receiver handles both the mouse and the keyboard. The keyboard is of a common membrane type, with 12 multimedia other shortcut keys. The keyboard takes in two AAA-sized batteries, too. Both devices have several power saving features that work to increase battery draw. The ORICO KM6116 goes for 89 RMB (US $14).
