Pros and cons

Pros

Two computers can share one display and set of input devices, reducing the need to swap peripherals manually.
Two stated switching options give a choice between using the unit's button and a desktop controller.
The listing gives a range of supported video modes rather than only one resolution claim.

Cons

No hotkey switching is supported, so changing computers requires the panel button or desktop controller.
USB connections are listed as USB 2.0, which may limit buyers needing higher-speed peripheral or storage connections.

What to know before buying

The video specifications are manufacturer claims. For 8K@60Hz, the listing says both computers and the monitor must support 8K and calls for a genuine 8K HDMI cable. Check all source, display, and cable capabilities for the intended mode.

Listing details to confirm

Listing details are inconsistent or unconfirmed: the title and feature text claim 8K@60Hz and 4K@120Hz, while the details also describe electrical switch attributes such as 2-way circuit and one position that do not clarify video performance. The title mentions a desktop controller and two USB cables, but the explicit contents list names only two USB cables, so controller inclusion is not confirmed by that list. The listing also describes two USB 2.0 ports but does not clarify which USB connections are provided for the computer links.

Aggregate ratings lean positive, with most reported ratings in the five-star category, but a smaller one-star share shows that experiences are not uniformly favorable. The figures do not identify what customers liked or disliked, so they cannot confirm switching reliability or the advertised video modes. Buyers should judge fit by the stated two-computer, one-monitor setup and verify that their equipment supports the mode they need.
