O2 Blast 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

The containers gave me about 3 uses per can . I thought the first can was a bad can but no all three were failures. Never will purchase this brand again.

One can out of the 3 pack worked well and expelled oxygen from the lever. The other 2 cans are sporadic and not effective. I will call for replacement.

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.

Easy to use Nice have on hand, esp with heart problem. It’s nice to have some O2 on hand to clear my head

This seems to help when I'm working in the yard or hiking in the mountains. If I feel tired and out of breath I take three shots of Oxygen and ready to go again. I think this is a good product for high elevations.
