Better Sport Device for Lung. (Blue)

I have wanted to try one of these breath training devices for a while. I often have post nasal drip that makes me cough a lot, so I hoped this would help clear my airways when that happened. I also get out of breath more as I get older, despite a lot of walking, so I hoped this device might also help me build a little lung capacity. It takes some practice to use this right. You will really feel a strong vibration from the device down towards your lungs. I have been using it with the medium ball that was installed when I got it, and do about 10 cycles of breaths in one sitting. I feel different after using it, like maybe I can breathe a little bit deeper, but at this point I'm not sure. It does get some moisture in it, so take it apart and rinse after each use. The first time you need to twist a bit hard to get the end off, and make sure you pay attention how the ball and cone go back in. If, like me, you forget, the listing has an illustration. I'll keep using it a couple times a day and see if it helps. It certainly doesn't hurt.
