EVOLVE22-Liter Pure Oxygen Canister with Breathing Cup | Portable Oxygen Can | Ideal for Home Use and Outdoor Activities | Designed by Firefighters | Made in The USA | Pack of 1

Don't buy this stuff! I did, that was the biggest waist of $65 ever!! All 3 cans didn't even equal 1 10oz O2 Blast!!! Do you a favor and spend $15 on 1 can of O2 Blast, you'll get more Oxygen!!!! I am writing this Ammendment to let everyone know that 'I made a mistake'! I should have contacted EVOLVE before I wrote the above review! After reading my review the management at EVOLVE contacted me immediately to let me know I would be receiving a full refund. And they are working to correct any possible issues. These guys kick ass! Quality business practices! Thank you, Michael. A

EDIT: The company shipped a new one extremely fast and it is working as it should. Would order again!!EDIT: After reaching out to the company they have offered me a refund. However. I have requested that before a refund is issued, I would like to try another can first. They have agreed and they are happily sending out a replacement can. I'm fully aware these things happen with any form of arisol can so I can't really fault the company and they were quick to tespond and the situation. I will be sending the defected can back ASAP and update my review asap.First Review: After only 3 uses the oxygen no longer released. It seems the trigger is not properly dispensing.

Both canisters ran empty after about 10 puffs and it was a waste of about $50 bucks! From now on I’ll stick with the Boost Oxygen Canisters! Terrible product!

I am a pilot so aviation grade O2 is an important safety tool. Also learned it is possible to provide O2 to an animal. Love the idea of the product - the ability to hold more o2 in a stronger can.I bought the 3 pack of evolve 22L here, and the Boost 10L at WalMart.While the Boost seemed to dispense more O2 than the Evolve, seller responded to my concerned review to let me know they had had a batch of defective dispensers and offered refund or replacement. They seem responsive and legitimate and the product idea certainly is a good one.

My husband suffers from Covid lung and he is very happy with this especially in this heat.

I usually buy the Boost brand but these appeared to be a better value. Once received them (3) one of the cans would barely seep with the trigger squeezed all the way in. I contacted the company and they were very kind about it and credited me back one can.So the other two cans were similar, very slow coming out and when I use this I am usually winded and want a quick shot to get my o2 saturation back up again and this just isn't what I was thinking it would be.

This is a good supplement. However, these cans don't always spray. I sometimes have to shake or tap them on something a few times to get them to release a spray of oxygen. I probably will go back to Boost as the cans work reliably.

I've been using this product for about 3 months and there have been no problems with the flow rate or any other issues. I'd definitely recommend this product to others who need supplemental oxygen.
