Boost Oxygen Portable Canned Oxygen, Natural, 3L

Works instantly! Helps with the shortness of breath due to altitude, helped with headaches. Checked on Apple Watch stats went from 89% to 98%

I am in cancer treatment which leaves me extremely anemic plus I have severe arthritis in both hips which makes walking a real struggle. The combination leaves me gasping for air after a 15 ft walk. Since I have started keeping the Boost oxygen around the house, in my purse and in my car it has made my life less painful. As soon as I feel out of breath a couple hits of oxygen helps tremendously. I just bought four 10 liter bottles to make sure I always have one nearby.

It's great when you have a headache or a hangover, cause fresh oxygen eases the problem

I HAVE USED THE 5 LITER, WHICH FITS A RADIO HOLSTER ON MY BELT, BUT THIS 3 LITER SIZE IS BETTER FOR "POCKET SIZE" USES. tHE "SCENT/FLAVOR" IS HELPFUL IN INSTRUCTING PEPLE HOW TO USE THE PRODUCT PROPERLY. oops, sorry about the all caps, folks

When using this product Boost was like a clean breath of fresh air.

I ordered the first can/bottle in a large size, but it didn't provide any help for my particular breathing issues. It arrived almost a week before the small, personal size can arrived. Since it didn't help, I immediately returned it without opening it. I added, refused and do not want, before putting it back in my mailbox to return and get a refund. I'm still waiting on that refund, and it's been, at least, 2 weeks.

It came in a torn up box and the can was empty I was charged for it and I have trouble returning it. BAD Business! Shame on walmart.

Product does nothing, I did a full blast of the entire canister (which is a small canister) and didn't feel any “Whoa!” like demonstrated on Shark Tank. I didn't feel more awake, I didn't feel anything, the only thing it did was make my mouth dry. It's a waste of money.

This does absolutely nothing. I don't feel any different. I thought it would be energizing to have this oxygen. If anything it wastes the energy putting the can against your mouth. Lol

First of all the size is incredibly small. Really isnt worth the price to begin with. Then upon opening it and giving to my disabled mother the canister was empty. I canno express how disappointed I was to find this out.
