Pure Oxygen Supplement, 10 Liter Portable Can with Custom Breathing Mask for Respiratory Support, Elevate Oxygen Levels & Reduce Recovery Time, for High Altitude & Sports Recovery (3)

Not as advertized

We have been buying this for a couple of years now. MY husband loves it, he uses this for when using his oxygen is not handy. it has really helped his quality of life. When my grandson got married, my husband had a small can in his pocket. No one could see it, no embarrassment, no lugging around an oxygen machine or oxygen tank. It gives him peace of mind knowing it is there if he is out and about and the need for oxygen arises.

Two of the canisters did not even work. Pretty much a rip-off. I purchased this before from drugstores. Never had a problem. I won't be getting this ever again

The items arrived on time. The oxygen bottle helps before and after exercising. Great price and easy to use!

I thought it was a fluke, but the 10 liters in this bottle doesn't last as long as a competitor's. I have been using supplemental oxygen before soccer matches for many years. One 10L bottle usually lasts three games. I can barely get two games from O2 Blast. I switched back to the other product to make sure it wasn't me that was just sucking more as I get old. NOPE! I just can't get as much recovery from this product. I tried a second bottle, same thing. Also, every now and then the nozzle trigger doesn't work well, you have to pull the trigger very high up near the cone.

Best thing to stay healthy. God bless
