I saw this product pitched on Shark Tank and didn't know portable oxygen was available until now. I was skeptical at first, but I had to try. I experience shortness of breath many times throughout the day and after using this product a few times, I can definitely feel the difference in my breathing and energy. I highly recommend it.

Gave me the oxygen boost I was looking for. A natural health enhancement product.

It was hard to tell if this worked. I had come back from Colorado where I had gotten horrible altitude sickness. I still had some breathing difficulties once I got home and at a lower altitude so I asked a friend who is a doctor and he suggested this product. I was not struggling to breath like I was in Colorado so I could not tell if it really helped. Perhaps if your in the middle of the altitude sickness it may work better. I kind of felt like there was not any air in it. It is a bit funny though to spend so much money on "air".

my mom uses this to help her for a quick relief for shortness of breath. hoping to get her on full oxygen soon. but, this helps

I purchase this after reading about the benefits of more oxygen in our system. It works as a pick me up when doing extra physical activities.

I ordered thinking this would be a great way to get a quick mid-day energy boost (similar to the results of using an oxygen bar). I received absolutely no results other than a headache from this product! Don't waist your time or money!

Great for working out. Gives me some extra energy. Wonderful product. Will buy again. The can is bigger than I thought. I believe this may help with headaches that I get.

This is made well and is of good quality, and the color is as shown. Matches the listing. A+++ Very happy with my purchase. Shipped out quickly
