As expected from Neutrik, the frame is solid and well built. Frame is easily dismantled from the connector eg. for painting purposes (frame and connector are held together by two screws).
Perhaps partly due to consumer nature of the HDMI connector itself these are not rock solid and will wear off eventually. In rental usage these last about a year after which the connector simply disintegrates. Before it does that, connector becomes so loose that no cable will stay steadily in place or make a good contact unless being supported - which, of course, is already game over.
For professional installations these are very handy, easily keeps your customers off the precious AV-equipment and while not being ultimately dirt cheap still offer a good bang for the buck. However, compared to Neutrik's other installation connectors (XLR, RCA) that cost less than half the price these should last much longer - rental usage or not. It should be noted that even the cheapest HDMI cables outlive this connector. It is pretty much vice versa what I was expecting when I first ordered these.
