@winterfelllvoyager75 I have had the Baster APX vest for only a week (after hospitalization for pneumonia) and I have been happy and grateful to have it. Not heavy. They programmed it to 6 for intensity (the middle therapy setting). it's not as strong as the 10 they were doing in the hospital when I was coughing horrendously. I just hope 6 is strong enough. Right now I, while the pneumonia has been beaten back through antibiotics, 6 seems fine. Don't know if it will be during an exacerbation. I'm glad I can bring it on my cabin vacation.
