Boost Oxygen Medium Revive Peppermint Aroma 5 Liter Canister | All-Natural Resiratory Support for Aerobic Recovery, Altitude, Performance and Health (4 Pack)

The items are great but there was no packing around the cans of oxygen. The package was lifted in my driveway in the sun. This may not be good with with this being oxygen.

I'm always short winded because I lost part of my lungs in 1996 and I never smoked. Unfortunately I worked in a printing company that had strong chemicals, without any ventilation. It ruin my lungs, which makes it hard 2 breathe especially when I walk a long distance. I try 2 way some everyday but the last 6 months have been terrible. It like I'm exercising while I'm trying to sleep. It makes it easier for me to straighten out my breathing.

It is compact, light and peppermint flavor make you realize if it is still supplying O2... I have a small plane and I do not fly at high altitudes. Mostly I am at or below 5000 and occasionally up to 8000'. But if I fly to Lake Tahoe kind of area even once a year this is handy to have since I may need to climb at 10000' to 11000' levels for less than 30 minutes or so and due to having a slight COPD problem, I keep 3 of these in my plane as a precaution. I thought, since it is not an expensive item, why not ? After I bought them I wanted to try it out and I climb up to 10,000' and my pulse-oxi-meter showed my O2 level dropped from normal 97% levels to 89% after 15 minutes at that altitude and I inhaled 2 puffs of O2 from this bottle and immediately saw my meter reading jumped up to 94% another 2 puff I was at 97% level again. So in my simple test I proved myself that it worked for me. What else I needed to know? Nothing really, that was enough for me! Now, I saw some people given low star rating to this product due to they are not getting the number of puffs O2... I don't challenge their experiences but still it is a good product and I got what I expected out of it! You may too!

At first I wanted to return it because it wasn’t helping me recover - I had gotten it for social anxiety. And it didn’t work for that. Then I tried it for orgasm headache and it was great for that!!

What a fantastic invention - these cans are truly lifesavers! The added scents are a nice touch, especially the peppermint. Because O2 is so light, the cans feel empty even when they contain product, which can be misleading!
