The A4Tech 4200NS Wireless Desktop is a full-size keyboard and quiet-click mouse set for home PCs and office desks that want to go cable-free on a modest budget.
This is one of A4Tech’s longest-running combos. It pairs the GR-92 keyboard and its round-edge keycaps with the compact G3-200NS mouse. The mouse clicks softly, which helps in shared offices and in bedrooms where someone else is sleeping. Drain holes let spilled tea run out instead of pooling under the keys, and the tilt legs give a steeper typing angle. The mouse wheel scrolls both vertically and sideways, which is handy in wide Excel sheets. There is no Bluetooth, so this set is for one computer, not for phones or tablets. The keyboard runs on two AAA cells and the mouse on one AA.
