Boost Oxygen Portable Oxygen Cylinder with 95% Oxygen - 20L, 4x5L Oxygen Canister with Oxygen Mask for More Than 400 Inhalations - Portable Oxygen Can, Oxygen for Home use (Pink Grapefruit Flavour)

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.
