Boost Oxygen Pocket Size Natural 3 Liter Canister | Respiratory Support for Aerobic Recovery, Altitude, Performance and Health (6 Pack)

My husband has COPD. He was concerned about going up to our cabin in high altitude this year because he has a hard time breathing. He is taking medicine for it, but still has trouble breathing. He bought Boost Oxygen. Every time he can't breathe he inhales Boost. Instant relief! He won't go anywhere without it. He buys the large canister for home and the small one for the car. Great product! Life saver!!

These are so worth it! Highly recommend! We took to colorado and used them hiking and they help so much! They last awhile too! If you are hiking or running or heavy exercise I highly recommend it gives you the breath back in your lungs! Packaging was great!

Great product for those of us that get altitude sickness. You can’t take this in a plane carryon or checked so I sent via Amazon to my son in Colorado so it would be there for our visit. Lasts a long time so the small size is great.

Nice to have, would buy more if not over priced.

Extremely helpful product...fits in your purse & provides approximately 60 one second puffs...

Easy to use. Felt great. Just the boost we needed. For long stays at high altitude I would recommend the larger container.

I used the first of the three cans and felt no difference in using the oxygen. I opened the second can and nothing came out. I observed the plunger depressed when I pulled the trigger, so that led me to believe can two was empty. I just opened can three and it worked, but again I feel no difference other than breathing regular air. I have had O2 shots before and I can feel the difference

I love the way it works, but in every pack there is at least one dud. I don't know how ANYBODY could prevent this, much less the seller. So understand that I am criticizing the manufacturer, not the seller. But it really is kind of a krap shute, so I would never recommend using this product as a medical device -- ever. If you are short of breath? Rush yourself to the nearest ER. Also? Don't overdo using it. You'll get a headache similar to an ice cream headache. I know this from bitter personal experience.
