I purchased my Power Lung at the suggestion of Dr. Burton Feinerman in May 2007. Within three weeks my peak flow had doubled and within 6 weeks it had tripled. My shortness of breath was reduced by at least 50%. My nebulizer has been in my closet collecting dust for the past 3 months and my inhaler is used no more than once a day.
I do 2 sets of 30 twice a day and it has become part of my daily routine. It’s easy and takes lessthan 5 minutes. I have severe COPD and my lung function is around 30%
Thanks for a fantastic product. I have recommended it to everyone I know with a breathing problem.
