O2 Blast 99.7% Pure Oxygen, 10 Liter Portable Can 5 Pack with Custom Breathing Mask, Increase Stamina & Reduce Recovery Time, Ideal for High Altitude & Sports Recovery

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.

I ordered the 5 can package . First can worked great but the other 4 were empty.

Good product.

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.

My first order was great. It helped out a lot. However, my second order was a bit of a disappointment. So far I have found one container out of five that had very little in it. I have two left. I hope they are all full and have good pressure.
