Get after a short use more air

I was just very skeptical, so a plastic piece with steel ball inside .... but it really helps! Already after 5 minutes application I get significantly better air and can breathe deeper. Especially a lot of secretion has not yet been resolved, but even so I'm very happy, maybe that will come, it had indeed used only once.

FYI: I have / had 2 weeks before the acute pneumonia, the worst time is with antibiotics rum now, but I just still struggling with shortness of breath, sometimes stinging in the lungs and always feel I get somehow not properly air , Especially with physical exertion. As I said, after 5 min application I notice an improvement.

You can tell right, as generated by these vibrations ball in the lungs. So I would buy it again. This company is also considerably cheaper than comparable products from the pharmacy, the cost partially twice or more, and it is the same building and they do only what makes this part. Shipping with Amazon as always top, was there the next day.
