Not good

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.

My husband has been using Boost oxy for a couple of years & Blast is a couple of dollars cheaper so I gave it a try. Epic fail. Only has a quarter of the oxygen Boost has & 2 containers barely worked at all. He uses them because they're lighter than a oxygen generator so to have new container have nothing is REALLY bad for him. Left him gasping like a fish out of water.

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
