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.

Horrible product, hofforible company. Promised Next Day delivery for $25.29. Product came # days late. REfused refund, said my claim had no merit, despite extensive documentation including their own emaails and website. THEN product seemed to be compressed air, not O2. AND 3 out of five cans were underfilled to the point barely any air pressure. SAVE YOUR MONEY. BUY A REPUTABLE PRODUCT FULFILLED BY AMZN.

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

Easy to use. Met my needs.

This stuff boost boast whatever it is all this canned oxygen does not deliver. I've tried them all the delivery factor is the main concern it does not deliver the oxygen correctly or not even at all. Don't waste your money on this happy horse s*** I had a replacement sent to me from the Boost people it was no better than the failed complaint of the initial product. Good luck

Like this brand than others Bought them for Colorado end up using all of them
