As a COPD recepient I take 3 deep breaths every night prior to sleep and good results are mentioned in my Oara app and other sleep apps! The inhale immediately gives me a feeling of satisfaction and a feeling of "lightness". Would not hesitate to repurchase your product!! 5 stars

Works great when needed

After my first order and try it. I place a 2nd order so I would have extra. I'm 70 years old and live a active lifestyle.

Truly helps in times of struggling to catch breath after intense training workouts. It's a life saver when hit with a bad COPD episode. Thanks for a great product!

We live in the Ozark’s and medical care is often 30-40 minutes away and having O 2 on hand makes a world of difference in many cases! We have a case or 2 in our prepping supplies because you can’t find it at the pharmacy without a Drs orders! Better to have then need it and have none!
