Undoubtedly anyone picking up these has eyed some of the cheaper ones. Well - don't. These are strong, they're durable and they're much easier to work with than many cheaper ones which try to minimize the amount of metal used. Particularly for doing tedious work like making snakes or stage boxes these are the only way to do it. And while a little superficial - the black does look very slick!
The one thing to note for some installs is that these are quite long compared to many other XLR connectors. That's great in that it adds additional strain relief and the long pins provide extra sturdyness, but for some they may have to consider using the angled connectors where space is an issue.
