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.

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

Easy to use

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.

I have altitude sickness and for those who don't know, it can just mean that you can't breathe well and get exhausted easily. This has been going on for a month. This oxygen was amazing at first. However, as time went on, it did little to help. I am still use it daily, in case it is doing something positive that I am not aware of. At first it did help me to feel better. It's easy to use, there's no taste, and the mask is comfy.
