This Amazon Basics USB-C hub works exactly as it should. The HDMI connection gives a clean 4K signal to my TV, and the wired Ethernet connection is stable. I’m getting around 900 Mbps through the cable, which is very good for my setup. Power delivery also works normally. Overall, a simple and reliable hub that does the job well.

Fairly effective.

While I didn't bother reading instructions, it functioned as I intuitively thought with some slight troubleshooting. For example, using the correct USB-C for power or data. Connections to support an external monitor needs power toggling occasionally. Patience paid off. Expected a subpar Chinese knock-off (with questionable safety standards). But works very well, but can get warm.

Lots of great uses for this.

This hub is essential for a Quest or other virtual reality headset if you want to stream HDMI video to it. It allows you to hook up the HDMI source AND a power supply to feed to the headset to prevent the battery from running down.
