Pros and cons

Pros

Combines video switching and shared USB peripherals for a four-computer setup.
Three USB-A and one USB-C ports accommodate a mix of USB peripherals.
The listed package includes four HDMI cables and four USB A to C cables, reducing separate cable purchases if the supplied lengths suit the desk.

Cons

Each computer needs both an HDMI cable for video and a USB A to C cable for data, so setup uses two connections per host.
Hotkey switching is not supported, so changing computers requires the unit button or desktop controller.
The listing says it is not supported with a docking station.

Customer feedback describes the switch as well-built and compatible with multi-system setups, with some customers also viewing it as worth the money. Experiences with reliability and connectivity are mixed, however. Reports include units stopping working, short service life and recurring screen flicker, alongside a complaint about HDMI 2.1 standards. These reports matter for a device expected to handle switching across several computers, particularly if stable display output and long-term use are priorities. The listing's video and compatibility claims do not resolve those reported concerns.
