UseBean HDMI Keystone Coupler 4K (2-Pack), HDMI Keystone Jack Inserts Female to Female Adapter Pigtail Extension Cable Snap-in for Wall Plate, (0.3ft Black)

nothing bad to say about such a simple product - they fit into a keystone port I had to install on a customer's table

Good product works well with what i needed it for

I have 48gbps "Ultra High-Speed" HDMI cables installed inside my walls, which theoretically can handle 8K60p video. In practice, I can successfully transmit 4K60p 10-bit video. When I add these couplers, they work with 4K60p 8-bit, but not with 10-bit. So they're certainly high-speed (maybe 18Gbps), but not equivalent to the 48gbps cables I'm using. I hope that helps!

I was expecting a simple HDMI connection, and was surprised to find a high quality connector. The cable itself is thick and feels great when compared to other HDMI cables. It worked perfectly as an extension I required. Not only was I surprised by the cable, but the seller reached out to me to ensure the cable met my expectations and encouraged me to contact them if I had any issues. Ordered many items, but that was a first for me.

Well constructed, looks great when installed. Also, the 4K video passthrough works perfectly. Tight integration with the two different standard keystones I mounted in the walls, and I am confident it would be useful for some time to come. Highly recommended.

Good build quality. Sturdy and makes secure connections. Worked well for the intended use without loss of signal fidelity. Would buy again as good value for the price

Simply too large and damaged a few trying to get them seated correctly.

Great adapters! Will definitely buy again!
