Oxygen Plus FDA-Registered Facility-Filled 99.5% Pure Recreational Oxygen Cans - O+ Biggi 3-Pack - Each Portable Oxygen Canister is 220+ Breaths, 11 litres - Restore Oxygen Levels w/Canned Oxygen

My kid was playing with my phone and ordered this, The vendor was 100% willing to refund this order, I chose a different route. 14,272 feet! Decided to test all these negative reviews against my own experience on Mt. Evans. I pushed it till I was gasping in the thin air, it was awful as my chest and head pounded and ached. That morning I was at 305 ft. where I live, with no acclimatization. Five slow breaths off of the can was instant relief. I followed up later with five more. Worked for me. Thank you!

Use daily

Came empty plus because its potage dangerous, couldn't send it back for refund

I left a 5⭐️ so you’d read this. I was skeptical before buying this. I purchased for workout recovery. I purchased and O2 monitor to test results as well as just based on how I felt. The cans are full of “Air” not O2. Hopefully it’s at least clean. I don’t have a way to test that. After several heavy workouts in the hot humid Virginia summer. I used this product repeatedly and checked my O2 with monitor and noted general recovery times. The results…… 0, nothing. The exact same as if it took some deep breaths. If this works for you it’s just the placebo effect. Like the promise from bottled water doing something special for you. Side note: O2 is highly flammable. If you use this on an open flame, it blows out the flame. I will sell you a ziplock bag of air for half the cost, so save money and Venmo me for a bag of air.

Went to some pretty high elevations on a month long trip. 9,500+ feet. And being from a lower elevation State, this oxygen really helped me keep my O2 numbers up. When I felt short breathed, just took a few breaths, all good!
