That's true, although connector quality does vary as well. And in his case, he was using an adapter, which adds some unique potential problems. Some connectors have electronic latches. I've had those engage before the connector and the adapter were fully seated, making it nearly impossible to push them the rest of the way together. Usually fiddling with the latch button is the easiest way at that point.

Also, some connectors have nasty white plastic, while others have really nice and usable handles.
