It's amazing! I have constrictive bronchitis and after having used this device for several days, I feel much better. I hope this helps other people like me as I wasn't sure it would work when I ordered it. I’m so glad I did!
I have had problems with shortness of breath for some time and have found that this really helps. It's easy to use and easy to clean, I'm delighted with my purchase.
After using it for a year, I haven't had to change any of the accessories nor have they deteriorated with use and the improvement in my lung strength has significantly increased. I love it!
It is very easy to use, practical, easy to wash and extremely useful for exercising the inspiratory muscles.
I used it to build up lung capacity after an operation. It was recommended to me by my therapist. The truth is that in the 2 weeks I have been using it, I have noticed a big improvement.
The product does what it was intended to do. What's more, it arrived on time.
