Boost Oxygen Large Natural 10 Liter Canister | Respiratory Support for Aerobic Recovery, Altitude, Performance and Health (3 Pack)

These are handy to have around. Easy to use. My mother uses them for occasional shortness of breath. I feel they are worth the money.

This stuff is not cheap, that is for sure. However, we tested this out on a recent hike at Big Bear Lake, while doing a little off-trail hiking and I can say it did help. I do not know scientifically if the results were physical or psychological, but after a particular climb to reach a geocache, I sure felt better taking a "few hits off the bottle." Have another hiking adventure at Yellowstone and Grand Teton next month, so we will give it another try, but for now, we are happy having a bottle along for the ride.

These are a must have for people with respiratory issues and higher altitudes. Went to a very high altitude on vacation with the spouse and these were a vacation saver. Cannot say enough good things about this product. When he experienced breathing issues, Boost really made it much easier to breathe. Worked great every time. No odor, weird tastes, just high quality, functional and very effective. Super thankful and grateful these were with us on the trip.

good stuff.

I got this product and thought the can was empty. IT IS NOT ! Had to think about it. Mildly compressed Air/Oxygen weighs pretty much 'nothing'. After trying a couple squirts, it works. After being mildly winded, this stuff works. Well worth the price. We'll see how many doses I get out of the can.

These are great for when you get short of breath and need a quick shot of oxygen. I keep one handy all the time. I’m 71 yrs old and it’s a comfort to know I have help nearby when I need it.

Worst packaging I have seen yet. Cans were banging around in the box. After using the product I can can’t tell if these was any effect. Interesting but not sure it helps me in any way.

The presentation is top notch. Easy to use and functions flawlessly. My only doubt is about its effectiveness. I can't honestly tell. It's easy to convince yourself that you feel some benefit. I suppose it's enough to make me reorder at least one more time. Of course it's not addictive, but it's the kind of thing that could easily become a habit. I definitely need to look up the science.
