O2 Blast - Pure Oxygen Supplement - Filled with 99.99% Pure Oxygen to Support...

Excellent to my headache in high altitude

After reading all the reviews and seeing so many negative ones I was really concerned about buying an empty can full of regular air like people were saying. Somebody said it was not real oxygen and mentioned something about blowing it on a candle and yada yada yada. So here's my personal experience. My wife suffers from Crohn's disease, AFib, and extreme anemia. Every time we go up North to an elevation of 6500 ft at our property in the pines my wife can only walk 5 to 10 steps and then has to rest and catch your breath. Last week she was having severe heart pains because she wasn't getting enough oxygen due to her anemia. I bought a six pack of these cans and today we went up to our property. As soon as we started walking from the creek up to the property which is about a 20 ft climb over 100 ft in distance, she got about 30 steps and was having a very hard time breathing with chest pains.. she took a one second hit from this can and within seconds the pain was gone and she was able to finish the track to where the house is. Just a few minutes ago she walked from the kitchen to the front door then down the hallway and back to the sofa. She couldn't breathe and was having very strong chest pains so I quickly got the can and had her take a hit from it. Within 3 seconds the pain in her chest went away. We have one of those little O2 sensors that go on your finger. I figured since it's worked twice now I want to see if it actually changed her O2... I didn't get the test it when she was in pain but when she was sitting there after taking that first hit her O2 was 97 which is regular. She took a one second hit from the can and 5 seconds later her O2 went up to 99 and stayed there for a good minute. I'm in good shape and I do not have any issues breathing in my O2 has never been higher than 97. So, I'm not saying this is a resolution for everybody but I am saying it works for her and it's not a placebo because these chest pains can trigger her AFib and the last thing we want is for her to have another cardioversion. If you don't know what that is, look it up. I'm giving this product five stars.

The top of this can is not a strong design. The majority of the oxygen is wasted. I was hoping there was a mouth/nose appartus that I could use--simialr to others.I will most likley order additional ones with an appartus.

Not easy to use. No noise or mouth piece. Like spraying a can of spray paint. Will not buy again.

UPDATE: Seller sent another set, and they were good. So definitely RECOMMENDING now! Original: This is unfortunate... has a metallic flavor/aftertaste. I assume it is just (95+%) oxygen - defeats the purpose of a refreshing breath of oxygen.

It’s unusable without a separately purchased mask. I bought three large canisters which I CANNOT USE since I saw nothing in print advising that a special attachment is required. I will be going back to BOOST—They’re immediately ready use, unlike this gravely disappointing purchase just taking up closet space. O2 blast, some users are emergency based and the fact that you all didn’t see fit to equip your device with a top that makes it immediately usable, tells me you’re not serious about ease of use, or interested in customers who need the lift due to health issues. By all means, oxygenate the athletes, but until you mask up the device, it isn’t a serious product.

Great Value for your money. This is the best price you can find. The product works. The air tastes and feels great. I find I am full of energy after use. It super easy to use and you'll feel it when you use it. Get this!

Works for quick oxygen boost
