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

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

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.
