No box. A switch that allows you to share a set of USB mouse, USB keyboard, monitor, and speakers between two PCs. This is a PC switch that allows you to operate two computers using one set of USB mouse, USB keyboard, and an analog-compatible monitor. It can also be used with laptops and Macintosh computers that do not have PS/2 ports. Even if you have two computers, you only need one set of input/output devices, saving space. It's a compact, cable-integrated type, so you don't need to prepare any other cables; you can use it just by having this product. It also has speaker input/output terminals, allowing you to share speakers between two computers. *When switching between Windows PC and Macintosh, please use a keyboard/mouse that supports both Windows and MacOS. Keyboards and mice that are Windows-only or MacOS-only may not work. Used for about one month. *No box.
