Boost Oxygen Large Natural 10 Liter Canister | Respiratory Support for Aerobic Recovery, Altitude, Performance and Health (4 Pack)

These really do work. You can prove it to yourself with an oximeter. My husband gets low oxygen occasionally. He can boost his oxygen back up very fast with this brand. Very good product

My 70lb dog has laryngeal paralysis and has episodes where he gets anxiety and his throat closes smaller than the diameter of a straw. At the emergency room he often avoided intubation with some mild sedation and oxygen flow. The emergency room is about 20 minutes away though and transportation is risky. These cans allow us to get oxygen to my dog to ease his laryngeal paralysis symptoms at home or while transporting him to the emergency room. This is not their original purpose but I do believe it saved my dog’s life on multiple occasions. I carry a can with me on walks as well as it is really portable. That being said, the quantity we need to purchase for our use case is large and these cans are pricey. Also, it is hard tell when the can is empty.

Product works great, that's why I'm buying again, although one of the cans I didn't use was empty upon opening for use.

Not much in each can. Consider it overpriced

Never be without this product. Keep plenty on hand. Easy to use these.

I have purchased this item on several occasions for travel use. We usually buy these several at a time. We have found that in many cases, if we buy multiple cans, often one will not work or break. This shows the break. When you try to engage the tab to activate the contents, it will break. Great idea for travel use but questionable construction. While Amazon is usually good about problem resolution, this item is not available for return or refund. If I could find a reasonable substitute I would, but there does not seem to be a good item. So I am left to just accept that failures are part of the package. Too bad

This is an amazing product to help when you need a boost of oxygen.

Product is great. However the cans were not wrapped in bubble wrap. Which I think they should be for shipping

Is basically just compressed air. No O2 benefit from me using it. Blood oxygen stayed the same.

Great. Lov it

Exactly as described, arrived quickly and without issue. The orientation wasn't obvious at first but is clear once you check the label. Would recommend.

I've got exactly 7 pumps out of it .... very disappointing !!!! Sono uscite fuori solo 7 inalazioni ... senza parole !!!

Tried different brand, so far this is the most reliable one I am using
