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

Great product thanks

Value for money breathing lot better when taken

One tank came nearly empty and when you inhale doesn't really feel like you inhaling oxygen

It’s good, I bought to assist with headaches although I need in larger quantities. 5/6 minutes on intake breathing isn’t long enough per canister and one arrived with the top green face pressure dispersal trigger damaged so it won’t release the oxygen. Overall disappointing but I’ll not be put off trying others.

almost instantly improved my breathing will certainly be very useful to me good size container feels like an oversized empty aerosol even though it is full very portable quality seems good very good value

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.Edit: I purchased another 6 cans of this product, and the above still applies. I have adjusted how I use this product, and they are okay if used with care. However, 2 of the cans were completely empty. This problem has been reported in these reviews before, so it seems that their quality control system is not functioning properly. And of course, I paid for 2 empty cans, and that is not acceptable. Perhaps I should have looked elsewhere for my oxygen supply…

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.

Excellent for a condition related to breathing, or just for when a sluggish veil drops!
