18L Oxygen Can with Mask and Tube - revitalize 99.5% Pure Oxygen in a Lightweight Portable Canister (2 cans),White Can

I have purchased this brand 4 times and have realised that I take about 3 breaths 4 times a week and after a week 18 litre container is empty and I feel no benefit at all it’s feel like just normal air, it’s a con , I gave it a good trial and after purchasing another brand and using that I could feel the difference and it lasted 4 weeks for a 15 litre container, so I have been wasting my pension on this crap , I would not recommend it to any body, I gave it a 1 star review because I have to , otherwise I would not give a single star 👎🏻.

Bad

Mask missing so cannot use !!!

No mask included, despite description saying that mask was included. Cans are empty, nothing is being released when button is pressed. Scam product. Would not recommend.

two cannisters, first one I would say was only half full, and now on the second cannister, and oxygen seems to be ok from the second one! I keep a count of the amount of uses that I use, to give me an idea as to how much oxygen is in each case! as this is a helpful product to me ! these cannisters are easy to use, and do help, and are a good price, as I seem to be waiting forever for an appointment from my local hospital, so these do help !

Ok

Got two cans expecting them to last longer. They feel oddly light when you first open them which made me wonder if they're actually full. Used one and did feel a bit more alert after but I can't say for sure if it actually did anything. Hard to judge if these are worth the price since I don't really know what to expect from them. Might be better if you know more about how to use them properly

Did not come with mask and tube.
