Many people have had the procedure; some have had great responses, others not so much. I think it depends on how many procedures they've done at the site you choose and how careful they are in the evaluation process. Most places will have patients who are willing to talk with others about their experiences if you ask. The best sites are those that participated in the clinical trials back in 2016 and 17. They have the most experience and were extremely careful about the evaluation process. Even those who didn't get much benefit mostly didn't do worse after the procedure, though it's still surgery and there's definitely risk of bad results. Side effects include collapsed lungs and pneumonia. Those are serious, but treatable.

I haven't

I haven’t had them and wouldn’t . I know someone who had them and they passed away within a year due to breathing failure.
