5-Pack HDMI Keystone 4K Female to Female Coupler No-Delay Snap-in for Wall Plate - White

Good product works well with what i needed it for

They snap into standard keystone openings cleanly, giving a neat and professional finish. Once in place, HDMI cables connect firmly—no loose connections so far.Build quality is decent for the price, but not amazing. These are great for basic installs where you want a clean pass-through, but I wouldn’t rely on them for repeated plugging and unplugging or very high-bandwidth signals like HDR over long cables.If you’re wiring up a clean HDMI wall plate for standard use, these are a great budget option. Just don’t expect pro-grade durability or guaranteed HDR performance.

No issues. Works like it should

Snaps right into any keystone jack and is a great solution for a clean, finished look. For those of us who prefer a clean look, these are a must.

Perfect

I have no idea if they work in 8K but they definitely support 4K and HDMI 2.0. I bought 10 for a project and they all worked.

These are good to have as a backup if you aren't able to install them in HDMI panels between your walls. I plan to use them as extenders for HDMI cables that are not long enough to connect from one device to another.They work just well enough for that and they all came new and functional. No complaints so far.

While these are great as a coupling device, they don't fit very well into wall plates. They tend to push back into the wall without much effort.
