Large Sport Orange Aroma 10 Liter Canister | Respiratory Support for Aerobic Recovery, Altitude, Performance and Health (4 Pack)

I’ve repeatedly order 4 pacs—very satisfied—on occasion one can is empty. Makes me wonder of the contents of the others? No way to tell? I still recommend. Recently ordered another pac of 4, but received only 1, then followed by another 1 only. Still waiting for the missing 2 cans. I have since ordered another brand. Last Update! Final two cans owed were delivered. They took a box of 4, and removed two to deliver the two owed. I’m trying one more time. We’ll see!

Can't tell when they are empty.

This thing is as advertised it's oxygen in a can but the problem is the attachment to the can comes loose and comes off and you can't breathe it like you should be able to It should be one piece It should not interrupt the flow of oxygen from the can

packaging was absent any inside wrap, the containers presumably bounced around for days, no idea if this works, doesnt seem to help. does have an orange taste

I use this right after hauling a deer out of the woods. the first breath or two does help you but with one tank, you probably get three to four breaths. it's not worth the money. with that big tank you should get more oxy than that.
