I own three of these and love them! I keep one in my car, one at home and one in my suitcase. I use it randomly throughout the day.
I'm an airline pilot and we spend a lot of time at high cabin altitudes, usually around 8000ft. And many layovers are in the mountains where the elevation is 7000-8000ft.
My first day using this exerciser was amazing....I swear my lungs opened up 20%. I've had a touch of asthma since I was a teenager and I don't know if it was that or with age my lungs weren't as open as they could be, but the transformation was clearly there. I could breathe deeply! Even when I feel my asthma, it doesn't slow me down like before.
Then I had my first trip after using this and I brought a Pulse Oximeter with me to measure my blood oxygen levels. The results were significant. My oxygen levels normally are 2-4% higher! Results I can measure....gotta love it!
And finally, I had my first layover at a high altitude airport...Rio Negro in Colombia. Over 7000ft above sea level and for the first time I didn't feel the altitude like before. I felt essentially the same as when I'm at sea level. That's a huge change!
You can't beat the price. It works....buy it!
