It Really Works! This little device does just what it says it will do. It loosens mucous so you can cough it up. I have asthma that was first misdiagnosed as COPD. For years I took the wrong medication. It didn’t help but I thought it might be keeping my breathing from getting worse. Then came the asthma diagnosis and medications with awful side effects. After the first time, I used the Turboforte my breathing improved as much as it does from using an inhaler. It may seem pricey but is very sturdy. More importantly; it really works!
