Boost Oxygen Extra-Large Rapid Response 12L Canister, 12 Pack

Came in handy for the wife on a trip to Colorado and the Grand Canyon. It is just weird. The can weighs next to nothing but is full of oxygen.

This works for when I have fluid on my lungs, and I just need a little extra air before my next treatment

Seems like it loses pressure after the first use. Worked great the first time and used a couple days later and I noticed the pressure was a less. Used it again a few days later and barely have any pressure left in the can. The air has no taste and very easy to use fitting comfortably around my mouth, even with a beard. I don’t notice any energy difference, but only one breath at a time is probably not going to be that noticeable. Thought it would be good for use after being in a smoky environment like a bar in Florida. Not worth the price if I can only get a couple of breaths out of a whole can. After posting my initial review, the seller contacted me addressing this issue. Hopefully it was a one time incident with the product and doesn’t happen again, but I do commend the seller for making it right. I’m therefore adjusting my review from one star to four stars for the seller contacting me and addressing my concern. I will definitely give this product another chance.

Works great especially when you're in the mountains at 8000' and have a cold. Really helped. Plus saved some money.

Easy to use, it seems to make a difference and I like that I can use as much as I need. It’ll be a staple for us as we explore at high altitude.

Good value!

quick delivery would be nice to know ho much is left?

The problem is you don’t know when it’s empty air still comes out
