Oxygen CAN with Integral MASK 99.5% Easy to use Pure Oxygen (36L (litres) Pack of 2) Pure Breathing Oxygen in a Lightweight Aluminium Canister 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.

Seems fine so far. As other people have mentioned, they do feel light / empty when you hold them, but they are still dispensing.

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.

Ordered 2 cans, which arrived promptly. However, the supposedly fixed dispenser on the top is not fixed at all and doesn’t fit so can not be secured and used. A complete waste

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.

Very useful to have on hand useful

I know this isn't supposed to be for medical use, but sometimes one just has to cope whilst waiting for an appointment. This stuff has been great when my inhalers just can't cut it. A quick squirt gets me over the worst. The product is quite large but as light as a feather and is easy and obvious to use. Totally brilliant.
