Lung Exerciser Device, Breathing Exercise Device for Lungs, Lung Expansion & Mucus Relief Device (Blue)

I ordered this a couple months ago, and wanted to give it a decent trial before reviewing. I think this really works well, and I can feel a difference. It really does loosen up the mucus and hake breathing easier and more effective. I highly recommend it. It is small, lightweight, and very easy to clean. Glad I noticed this item!!

This is a simple and well made device. It is easy to adjust the resistance and performs better than I thought it would. While it is hard plastic, there are no flimsy parts to worry about.

It's the strangest thin! Blowing into this "thing" creates a "bouncing" in my lungs that completely broke up my bronchitis. I suffered terribly until a nurse friend of mine told me about the Flutter Valve. It really works! What I, also, like about it is that it can be used to strengthened weak lungs to help take in deeper breaths. It's great quality and usefulness for the money. It's so easy to use, also.

Have been using this for over a couple of weeks now. Simple to use and clean, compact, noticeable improvements in breathing, and clear lungs.

This product has made a significant improvement to my COPD. I use it regularly and it has helped clear my lower lungs and keep them clear. I would heartily recommend this to anyone who suffers from COPD or other chest congestion issues.
