Boost Oxygen5 Liter Natural Pure Canned Supplemental Oxygen Bottle with Built In Mouthpiece for High Altitudes and Recovery, Natural Flavor (9 Pack)

I have asthma and this helps me with my breathing problem. However, I am elderly and am trying to live on a very tight, limited income. I'm know this does help me to breath better when I have an asthma attack. However, it is very expensive and I struggle paying for it. Looks like I will not be able to purchase it again since it is so expensive. Plus, the canisters were just thrown in a box with no packing which caused them to bang and clatter against each other. That is not the proper way to ship something like this (especially since it is so very expensive).

Several of the canisters in the shipment had hardly any pressure! They were almost depleted!

Very good oxygen supplement. Good quality. Portable. Light.
