Works fine...as long as you are sinking it into a wall. If you are using a surface mount box there probably isn't going to be enough space for the cable ends to make a nice turn. Needs a longer, and more flexible cable on the plate.
I bought 75 of these and paid an installer to put them in multiple classrooms in our building. The first one to be used led to the HDMI port being push out the back of the plate leaving it unreachable inside the wall. I had to remove the plate to fish out the cable. Turns out the HDMI connector part of the plate is actually a separate piece and is not integrated with the plate itself. The plate cracked, so trying to reassemble it was a failure and led to me throwing it away and installing a new one. I ended up reversing the plate so that the dongle is exposed on the classroom side of the wall. This will keep the HDMI connector from being pushed into the wall, but I fear the exposed dongle will be problematic in some way. Plus, it just doesn't look clean and neat, but it is more usable this way.
All in all I absolutely like the idea and neatness of the design, but the fact that the HDMI connector is easily pushed into the wall makes it a no go. At this point I am not sure what to do with all of the ones that have been installed.
PROS: Looks good, easy to install. Good price.
CONS: The HDMI connector is not part of the plate and is prone to being disconnected from the plate and pushed into the wall causing the user to have to remove the plate to fish out the cable.
Installed a couple of these this weekend to route my HDMI cable through the wall. Of course, you need to use a low-voltage wall plate to provide access. Due to the length of the dongle on the inside of the wall, though, it was a bit tedious to get the attached cable and plug pushed into the wall cavity (with insulation). A bonus is that the form factor is a standard "Decora", so if you wanted to mount this in a 2-gang plate with speaker wires or something else, it can easily be done.
One other thing: Due to this being installed on an exterior wall, I installed one of those cheap foam outlet insulation pads between the plug and the cover plate. The cover bows out in the middle quite a bit, but this should help mitigate some of the airflow through the plate.
In my living room which has my home theater setup the television panel is wall mounted and all of the components like the receiver are hidden in a closet in an adjacent room. On the wall directly under the television was an old and unused coaxial cable TV outlet which I replaced using this HDMI receptacle to allow a laptop or other similar temporary device to easily attach to the TV and home theater receiver. This worked out great and it looks very professional. .
PROS: Easy install into a wall box, simple connection all hardware was included you only need to buy an HDMI cable.
CONS: Would be cool if it had a cover to hide the HDMI port when not in use but this isn't a big deal.
Needs to be an integral unit also needs a connection-securing mechanism
The HDMI plug portion of this unit is not an integral part of the wall-plate. Consequently, whenever I try to plug in the cable, the plug portion pushes out and fall back inside the wall. I have to remove the entire wall-plate assembly, make the connections, and then screw the wall-plate back to the wall with the cable already plugged in. Obviously, this does not make it easy to plug and unplug cables in order to switch input units. The small piece that contains the HDMI female plug needs to be solidly glued into the wall-plate, so that it cannot come apart.
Also, the in-wall connections can easily come unplugged. I had to use a lot of tape to secure the connection. Some sort of locking mechanism needs to be provided so that the in-wal connections are secure.
CONS: Wall-plate falls apart.
No locking mechanism for securing the inside-the-wall connection.
