3 Pack Large 10-Liter Boost Oxygen Portable Pure Canned Natural Oxygen Canister Bottle for High Altitudes, Athletes, and More, Flavorless…

A great item ,works great. Only problem was ups dropped off at wrong address Was all most two weeks before a woman and told me about it.

Helps regain your 'breath' quicker. I wish I found this several months ago during very humid weather in July and the crazy Canadian wildfire smoke that comes down into Wisconsin. But during workouts in garage with limited AC, the humidity and air quality isn't optimal and going outside it hazardous. This canned O2 would have been just the ticket after doing some strenuous workouts and not being able to catch my breath. I have this now in Nov since October and while having similar shortness of breath, I take 3 to 4 hits off the can and seems to help vs just sitting in front of a window AC breathing the cold air. So far its lasting a long time. I mark the bottom with a sharpie counting down the number of 'hits' taken and so far its around 30 and still some left in the can. I originally saw this on Will Tennyson's YT channel where he tried it out. I didn't know this stuff existed and contemplated getting an Oxygen tank and mask but so much regulation and hoops to jump through. Here you can just buy it and use as needed and not very bulky. Its as heavy as an empty beer can. While this takes me back to watching the original Total Recall movie with Canned Air on Mars, its definitely got its place in my gym being an older lifter.

I think this product is way overrated, great advertising, packaging etc. But definitely don’t get all the buzz and great effects that they say or I read about. If I’m on top of a mountain, it might be great, but at sea level nothing so noticeable

Great product - many purposes! Only complaint is this shipment arrived in big box that was pierced open in several places! Use smaller box and pad to avoid movement of cans.

Easy to use
