I used it yesterday (twice) and the day before (twice). I felt it exercising my lungs!

The Power Lung has increased my lung compliance and has enabled me to have a larger tidal volume breath each time I breathe. This has enabled me to at least breathe stronger with less tachypnea when training at my lactate threshold.
