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

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

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

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.

I got this today and can't use either cans, the green mask does not stay on the canister you nead to hold it down quite hard to keep it in place which you can't do whilst it's on your face because it hurts. I have ordered a separate one with a sesperate mask hopefully it will work if not it will have to be returned.

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.

Unfortunately my elderly dog passed away but for his last week, I got some oxygen for him to help him. He wasn't really struggling to breath but it did help him a lot! He was sleeping a lot as you expect from an elderly dying dog. He even fell asleep during eating, which he did by spoon in the last 3 weeks. But as soon as he got some oxygen he perked up a bit. I also gave him some oxygen now and then when he was sleeping. I want to believe that it helped him

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.
