Boost Oxygen Portable Oxygen Cylinder – Personal Oxygen Canister, Up to 60 Uses, Pocket Size Oxygen Bottle with Mask, 3 Liter (Menthol Eucalyptus)

I picked this up mainly out of curiosity, but it has actually been pretty useful to have around. The cans are compact, lightweight, and easy to carry or store, which makes them convenient for travel or keeping in a bag. The bursts are clean and easy to control, and it’s simple to use whenever you want a quick refresh. It’s especially nice after physical activity or when you just want a quick boost. The packaging feels solid and the cans lasted longer than I expected with normal use. Overall it’s a simple product that does exactly what it’s supposed to do, and I’m glad I decided to try it.

I like this product, just hate that it's so expensive. Also, they advertise 60 1 second inhalations for the 3l - I find that I get more around 20-30. The product does work, though.

Arrived quickly. Easy carrying.

My daughter has several medical conditions that cause fatigue, dizziness, and sometimes confusion. The pocket-sized O2 canisters that she can carry in her purse of pocket have been lifesavers. One or two puffs when she's feeling ill perk her up and allow her to finish her work shift. These were recommended by her Physical Therapist and they have helped a lot.

Hard to tell the effectiveness of the smaller size -- need something bigger and more robust. Very easy to use and clean too.
