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

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

Good size for handbag.

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.

Good product

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

One measly puff out of it. And that didn’t do much for me. Don’t bother with this product it’s almost a scam. Definitely do not rely on it as a booster if your out hiking or exercising.

I didn't really notice any difference after using this. I used a spO2 instrument to measure my oxygen levels before and after taking the oxygen, and there was no difference (if anything my O2 levels decreased). Not convinced that this makes any difference whatsoever. Also not convinced this is value for money.

Muchas gracias. Llegó en muy buenas condiciones. Llegó antes de la flecha señalada. Excelente. 👍🏼

Ich bekam Atemprobleme. Würde ich nicht noch einmal kaufen.

I use this a couple of times a day, one big breath each time. Definitely helped post covid and with clearing air pollution.

Este producto es una castaña no sirve para nada

work great!
