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

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

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.

There’s not a lot I can say about this product - it’s Oxygen in a can, with an easy to use mask-like top, so all you do is put it over your nose and mouth and press the lever and breathe in the lovely oxygen.I have a breathing problem, so I like to have oxygen around and use it when I might get a little out of breath, or feel like a perk up. These cans are convenient and simple to use, and they’re good value too.I’ve nothing bad to say about this product, I’m very happy with it. Two thumbs up 👍🏻👍🏻

Sadly, the integral mask is faulty. Can not fix it on the cylinder. Can not use and it seems empty. Not great
