This was purchased to connect a new PC to an existing AV installation. It meets that need well. I did need to change the DP port used while setting things up, and the clip on this unit was quite hard to release, especially when working in a confined space. However, this does give me confidences that the adapter won’t fall out while the system is in use.
It has only been in use for 3 weeks, so I cannot comment on durability, but the build seems suitably solid.
