O2GO 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

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

Empty bottles, not a good product.

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.

Ordered these for the winter - expect I’ll get a cold and bad chest and O2 always alleviates the effect

I was expecting to get more than a couple of minutes use out of it. The cap kept popping off one of the cannisters and wouldn't click back into place. I paid £4.99 for next day delivery, but they took two days to arrive. I wouldn't buy again.

Useful for shortage of breath for mild copd sufferers easy to use and reasonably affordable

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.

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
