HDMI Keystone Coupler, Gold Plated HDMI Keystone Jack Insert Female to Female 3D 4K Coupler Adapter for Wall Plate (Black/5 Pack)

Only one broke after several time of cable movements

They were great so far. No issues, but it should be said that I am not going above 1080p and more than likely lower. I have no idea how they would be at their claimed max. The only slight annoyance is that the connectors are very tight. I have to really push in the HDMI cable ends. Otherwise good product. I actually ended up buying a few more.

My goal was to use two of these, as I would assume most usage scenarios would be, input and output plates for clean installs with no cords coming out of walls anywhere. I was able to test the bandwidth using a pc and changing not just the resolution, but HDR as well. Unfortunately what worked perfectly with the optical HDMI cable making the run, would not work with 2 of these adapters, if it would work at all it would hickup every few seconds on the audio or both video and audio, but usually just not work at all. 1 adapter worked, and I may use one in my theater after a long testing period, but I'm skeptical. Still, it does what it says it does technically, so 4 stars.I think I'll have to wait for either a new type of adapter, or till 8k rated ones hit the market, so I can use them for 4k, haha.

Nice finished professional look of hdmi in the wall but does add a coupler which degrades signal level. So give and take of form over function as 4K signals more sensitive. Power booster solved the problem

So first off, the item is as described. And it works.I thought it made sense but after installing it, it was not good. Partly this was because I was putting it in a 6 port wallplate. Instead of easily pushing all the wires into the wall, I had this thing pushing an HDMI cable up. I had to hold it at just the right angle to get that in first and then tilt and force in the rest of the cables. And even once in, it barely cleared the depth of the drywall. I'm replacing it with a non-90 degree one.Maybe if you only have a 1 or 2 port plate and a fairly flexible cable this would work well.

They may fit your plates, they didn't fit mine. Not without hacking them up.The plastic boss on each side is too wide preventing a second like keystone from squeezing in next to it. They'll fit next to a keystone that doesn't have a similar obstruction.I shaved the plastic off one of each pair with a band saw to make them fit.

They work well, but the angle makes it so that you can't put any other keystone above or below it

I ordered these to replace the HDMI keystone pigtail connectors. Where I am running the HDMI cables in the wall is fairly narrow, so I thought these would fit better. Once I but these connectors in line, got no signal on HDMI. Once I put the old connectors back, the HDMI signal came back. These connectors flat out don't work and don't allow HDMI signal through.
