Bought a bunch of these for patch cables, seemed decent enought from the photos, so what the heck. They are better than I thought they were going to be, the metal is thick and sturdy, the thread is good and solid, but best of all are the soldering contacts - they're very well laid out, in a way where you really don't need to worry about jumping the contacts, also the metal itself takes well to solder AND they take a pretty thick cable! Only somewhat negative with these jacks is the fact that they unscrew easily, which can be a bit annoying, but as with all jacks, I just put some plumber's tape on the thread and it stops it from unscrewing forever. Definitely would recommend, rock solid jacks.
