Get winded sometimes? Keep one of these handy you’ll be glad you did

Great for those times you need a little boost or shortness of breathe from COPD. Decent price. Will buy more as needed. Convenient.

BIG DISAPPOINTMENT Dont WASTE your money on this product - opened 1 it didnt work at all so I opened them all - 2nd opened didnt work at all either - 3rd barely 10 breaths in it and then the last 2 worked - will see for how long? so 2 out of 5 worked- and I believe I cant return them. So will stick with what I know works have purchased BOOST PRODUCTS 3xs and never a fail purchased.

As described, on time and packaged well. They get me through the day as I have COPD

Do not buy these. Received today one is empty. So of the others are low (never used. 0* not returnable. Had to leave a rating to continue -*-*-*-*

Easy to use. Met my needs.

Just believe me, little oxygen, no pressure. Alot of waste around the face

Had an issue with two of the cans not working. And the fit over your mouth Does not work very well.
