I recommend this product to anyone Being a person who suffers with asthma,and shortness of breath, this is a great tool to help improve breathing. Breathng Exercisor I have COPD and hope this will help me breathe. It WORKS! I have asthma which I am sure I got from years of smoking. I do not smoke anymore but as I got older, it got harder for me to breath and exercise. My doctor said I do not have COPD which is good so I thought I would try this out and see if it really would work on my breathing muscles. Well it does. I now feel like I can breath deeper and I do not get out of breath as often. Thanks for a great product. Great My daughter-in-law has asthma so I purchased the second one for her use. Works as I says I use the product as intended. I feel a slight difference in my breathing. So far after a few weeks this is working You can take it anywhere, it is very easy to use. One breath at a time Easy to use, effective device to improve breathing. Its compact size is a plus.
