Portable Oxygen Can with Breathing Mask for Travel, 10L, 5-Pack

I received the new mouthpiece design with the BLUE trigger. Of the (5) purchased, (2) of the cans did not initially seem to work. After experimenting by tightly gripping the mouthpiece against my face with the trigger held in, I pushed the can towards the mouthpiece while turning it slightly back and forth. Then the O2 started to come out. I informed O2 Blast of all my findings and indicated that they were still fine tuning the installation of the new mouthpiece. Overall the quality of the mouthpiece design seems adequate and easy to use. Customer Service for this product is Exceptional and they quickly sent out replacement cans. If O2 is what you need, I would recommend this company and their products. This is my first purchase of O2 from anyone so I can't testify to the performance boost of using it at this time. Statistically O2 should improve your energy levels. The cost for this product seems in line with other companies products.

Works. Not the same sort of delivery as the Boost version in that it seems lesser but still does the job just fine. I have COPD but my O2 levels rarely go below 95%. My Dr. says this sort of thing really isn't necessary for me and aren't recommended so now I have a bunch of cans of stuff I don't need right now. I can attest they raise my O2% and they work. The cans of this and the other one mentioned are super light and feel empty but they are not empty. It's highly compressed gas and liters of oxygen weigh next to nothing. (22.4 liters of Oxygen weigh something like 32 grams as a comparison if you know your periodic table) Still, I keep a can of it with me as I'm working. I do deliveries and it's physical. Helps to also bring your oximiter to check as well.

not much o2 in the can.. the O2 last for very little time....

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.

Has more power in the spray and the cans seem to last a little longer. Found this O2 Blast when I was trying to save a little money.

Valves quit working

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

Works well
