The HP Wireless Mouse 220 in black is a sleek and reliable optical wireless USB mouse with a receiver that offers a maximum DPI of 1600. With a compact design measuring 5 inches in length, 7 inches in height, and 2 inches in width, this standard mouse features a scroll wheel for easy navigation. The mouse is easy to use with wireless connectivity. Ideal for everyday use, this mouse is a practical choice for anyone looking for a high-quality and efficient pointing device. Comes with a battery, but it has been sitting in my drawer for a long time so I cannot guarantee that the battery will work.
