## At a glance

- Switches one HDMI monitor and shared USB peripherals between two computers.
- Offers a body button and a wired desktop controller for changing the active computer.
- The listing claims up to 4K@60Hz and requires a high-quality HDMI 2.0 cable no longer than 3.3 feet for that claim.
- Claims plug-and-play operation without an external power supply.

## Pros

- A single monitor and keyboard-and-mouse set can serve two computers, reducing the need to reconnect peripherals by hand.
- The separate wired controller can be placed on the desktop while the switch is kept out of the way.
- Two USB 2.0 ports are listed for a keyboard, mouse, or other USB 2.0 devices.

## Cons

- USB peripheral connections are USB 2.0, not a higher-speed USB standard.
- Hotkey switching is not supported, so changing computers requires the unit button or wired controller.

## A good fit for

- Setups that require USB 3.0 peripheral ports or confirmed Mac compatibility.
- Setups without HDMI ports on both computers and the monitor, or that depend on conversion adapters.

## Customer feedback

Customer feedback highlights ease of setup, convenient switching, perceived 4K picture quality, quick switching, and a tidier desk.
