I just wanted to chime in with my 2 cents 🙂: In my opinion, every single type and brand of pole is prone to problems of one kind or another, and a lot of problems fall under the category of user error (not all problems, obviously, just a lot of them ). Everyone is different: need different features, put different kinds of stress on the pole depending on their weight, moves they do, etc. and encounter different problems with different kinds of poles because of that.
I think what it comes down to is finding the type of pole that you feel meets your needs and then making sure that you do lots of research on how to take care of it - read up on what to do to avoid problems and what to do if you do have a problem. Stuff may still happen, but you decrease the chances by taking good care of it.
People didn't like the original X-Poles with the threaded joints because people were getting them stuck, so they came out with the X-joints; now people are having problems with those, too. I have one of the originals and while my joints do get stuck occasionally, I've been around long enough that I know several tricks to getting them to come apart and have always (eventually) succeeded. So I would say if you've decided the X-Pert is the pole for you, then go ahead and do it - just read up and make sure you take good care of it. 😀
