A small USB switch that lets two computers share one keyboard, mouse, printer or scanner. Video is not switched, so it will not replace a full KVM.

Overview
Not a full KVM with video, this is a four port USB switch that hands one set of peripherals to either of two computers. A push button controller handles the switching, and the case combines plastic and aluminum.
The reason to buy is one keyboard, mouse and printer shared by a desktop and a laptop through a short push of a button. The limit is that no monitor sharing is included, and some spec fields look like generic switch data.
Who it's for
A home office with a work laptop and a personal desktop sharing accessories will use it daily. Anyone expecting to share a display, or needing a fully documented spec sheet, should choose a KVM instead.
Pros and cons
- Shares peripherals between computers
- Manual and automatic operation
- Two cables included per the title
- No video switching
- Some spec fields look generic
- Printer sharing details unclear
Performance notes
The switch reassigns the connected USB devices from one computer to the other, so each machine sees them unplugged and plugged back in. Speed depends on the USB version of the devices and the computer ports. The controller makes switching quick without reaching behind the desk.
