Hi Boost Portable Oxygen Cans Pure Breathing Oxygen with Mask, Tube, Made in The UK, 3 Pack 10L Cans, Total 30L Capacity, 0.5 Kilograms

Works as it should

Awful product. Came almost empty with no pressure. Canister 2 was only slightly better. Avoid

Gives a boost especially when breathing is bad

I didn't experience any noticeable improvement Not able to say, one way or the other whether oxygen was available in cannisters

Really difficult to smooth out the plastic tube and the face mask. It made using the oxygen a real struggle so we gave up and bought the oxygen with mask attached even though it is more expensive. Can’t honestly say if the oxygen is helping but hope it is.

These handy cans of oxygen are useful to give your lu gs a quick boost but over my past few purchases, I have noticed that some of the cannisters empty mega quick despite only infrequent use & only using the 2 second press. Also it is wise to give each can a quick test press when they arrive, without the pipe attached, to hear if any O2 comes hissing out. I have had a couple of cans that have been empty. Also wise to keep a press button assembly once you empty a can as I have also found a couple that fail to press. Other than that, handy to have. Be lucky.

The canisters came on time and intact my wife uses them and the price was really good many thanks

Only lasted 5-10 seconds before it ran out, that’s the first can in the bin. Should had read the reviews before buying. No stars for this item, money wasted. Had to give one star lol.
