O2 Blast - 4L Portable Oxygen Can with Flip-Top Cap, Compact Design, 12-Pack

Good stuff

the canisters were very small. Smaller than a 10oz soft drink can, and there was only enough "oxygen" in one can to draw 4 breaths. I use oxygen therapy for some medical issues and this choice wasn't what I was hoping for. No, I would not recommend this product to anyone, based on price. It's way overpriced for the value. The canisters are much small than expected, and the contents of each of the four cans was only enough to take 4 breaths.

2 of the bottles were very low . I only got to use them 2 or3 times

Definitely gives u a blast of energy like it thanks

I always wanted to try these out. Seemed intriguing since I had heard how they pump oxygen into the casinos in Vegas to keep people energized. Also, as a smoker, I thought it couldn't hurt to get an oxygen boost any time. They seem pricey for a can of air, but I thought perhaps this is just more high quality air than that we normally breathe. So, $16 in and I puffed away at the can when it arrived only to experience...nothing. I won't say it didn't have any benefits. They were just the type of benefits not immediately noticeable. The healthy buzz I hoped to get off a few puffs sadly didn't occur. However I might buy these again if I had big pots of money buried in my backyard and could easily afford to spend money on cans of air. Pure oxygen, but still air.

I thought the "air delivery" was weak. I was using this product for post surgery help, the cans didn't last more than a couple of days. I won't be purchasing this again.

As good as any canned oxygen in a travel friendly container.

Arrived fast, can't tell if it's pure oxygen but I trust the brand
