Cylinder - Portable Oxygen Cylinder for Breathing Up to 100 Uses |Pure Oxygen Can Promotes Breathing, assists with Hangovers, Colds, & Revitalizes Lungs (Menthol-Eucalyptus - 5L)

Great for emergencies.

Easy to use and just what was wanted. Very effective.

Absolutely a con do not buy have contacted the company for refund with no help . If you don’t believe me use an oxygen monitor it will make no difference to the reading one bit . Yiu might as well just breath deep normally

Good size for handbag.

Good product

WASTE OF MONEY. SEEMS LIKE A CAN WITH A TINY AMOUNT, DO.N'T RELY ON THE PRODUCT FOR COPD.

Utter rubbish. You’d be better off sticking your head out of a window. No noticeable effect, it’s just a can of air. Not medical grade and certainly not helpful for anything apart from emptying your wallet. It lasts about 20 presses and does not sit tight against the face. Complete rip off.

Bought it for my friend who has lung disease. He said its not oxygen. Its just compressed air.
