Portable Oxygen Canister with Integral Mask, 99.5% Pure Breathing Oxygen, Two 18-Litre Doses Total 36 litres, Pack of 2, Lightweight Aluminium, Made in The UK

Easy to use, instant shot of oxygen, very handy if you find you are in need of oxygen. Easy to store.

Excellent

They seemed to work at first but maybe the valve was broken (on both) as they went empty ridiculously quickly.

Handy size, easy to use but the face mask, I found to be rather uncomfortable. May just be me being used to the softer type oxygen mask.

It appears that the canisters might be empty!! My husband has not had chance to try them but certainly they feel empty and the only instructions for use are printed on the side of the canisters. He will try them out over this weekend but never having had to have oxygen for home use previously he is not sure what to expect from the canisters

Very useful to have on hand useful

These cans will soon empty if you depress the lever fully. They release the oxygen full blast, way faster than you can breathe in, so most of it is wasted. The trick is to depress the lever very gently to release the oxygen at a slower rate, one that will allow you to get the oxygen at a more breathable rate. Even then they don't last long. Not very cost effective.

The canisters were a bit bigger than we expected, but not an issue. Good fitting nose piece, so inhaling is easy and you don't waste oxygen. Would buy again.
