Portable Oxygen Can 95% Pure O2 10 Liter Oxygen Cylinder, Oxygen Supplement, for High Altitude & Recovery Home Use, 3 Oxygen Tanks

UPDATE; they refused to say what actual MEASURED oxygen % is! It is NOT 95%!!!They also refuse full refund - they did offer 50% (which is what I assume is oxygen %).If you are expecting/need 95% DO NOT GET THIS. (Other brands are better.)I don't have an Oxygen analyzer, but according to flame test this compares to about 60% or less pure oxygen. (Big disappointment, won't be purchasing this anymore. )

lo compre para vacaciones a Colorado y nos ayudo mucho ami familia y mi un paquete muy bueno

I have used other brands of oxygen for altitude sickness and they give you a "shot" or "burst" of oxygen and these ones didn't. It clearly says on the can "Enjoy a burst of oxygen" but i couldnt tell if it was even coming out at all. Also, didn't help me with altitude sickness.

perfect fits my everyday needs, very happy will buy again.

Well it kept my friend alive until he made it to the hospital. I am a believer

I requested a refund, they asked for a pic of the original packaging and a receipt.I do not have either, the packaging was thrown out after I opened the product.The receipt is that I bought it from Amazon.

The dispenser lever breaks iff very easily leaving the canister useless. The slightest bump causes the lever to fall off.
