Review on Microsoft Wireless Optical Sterling 69J 00002 by Boyan Chakarov ᠌

Batteries last almost half a year, nothing more (scroll and two buttons). Works well with D-Link KVM-221. It is not whimsical to surfaces. The signal from the base is excellent at a distance of no more than a meter. Some pros: wireless) The rotation of the roller is clear and not heavy. The key travel is small, there is no backlash. Its cons: Heavy, the paint wears off quickly (bald patches appeared on both keys and in the area of ​​contact with the wrist in a year).
