Girl to keep in car & purse

the canisters were very small. Smaller than a 10oz soft drink can, and there was only enough "oxygen" in one can to draw 4 breaths. I use oxygen therapy for some medical issues and this choice wasn't what I was hoping for. No, I would not recommend this product to anyone, based on price. It's way overpriced for the value. The canisters are much small than expected, and the contents of each of the four cans was only enough to take 4 breaths.

It is what it says it is. If walking across a large parking lot or shopping in a big box store causes you to experience shortness of breath you might want to try this O2 supplement as a temporary fix then talk to your physician about other more permanent treatment options.

I'm on Hospice care. I recently had a bad fall, bruising my ribs along with other parts. I'm on Oxygen but when I lay down my bruised ribs will not allow me to take a deep breath. This bottle felt empty and I didn't hear a sound , taste anything or feel any breeze. I thought it was a scam! Not at all. It was like taking a deep breath finally! I know for the rest of my life here, I will always have a bottle near by! Which it came out years ago when I was a runner. The Drs just give you a rescue inhaler. It makes your heart go crazy. My Angels were looking out when I found this page. I encourage everybody to keep these easily accessible. Especially if you do sports! This could be the difference between life and death for someone.

I always wanted to try these out. Seemed intriguing since I had heard how they pump oxygen into the casinos in Vegas to keep people energized. Also, as a smoker, I thought it couldn't hurt to get an oxygen boost any time. They seem pricey for a can of air, but I thought perhaps this is just more high quality air than that we normally breathe. So, $16 in and I puffed away at the can when it arrived only to experience...nothing. I won't say it didn't have any benefits. They were just the type of benefits not immediately noticeable. The healthy buzz I hoped to get off a few puffs sadly didn't occur. However I might buy these again if I had big pots of money buried in my backyard and could easily afford to spend money on cans of air. Pure oxygen, but still air.

Not much in the cans. Not worth the money

Great price good product good seller

Doing the job.
