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

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.

I received the 3 can package on time and well packed. 1st can produced 3 puffs and was exhausted. 2nd can, same story. I opened the third can, (all factory sealed) and it seems to work normally. Since these are a no-return item, I'm charging off as a not lifechanging lesson. At least I can warn others off this inconsistent product. Waste of time and money.

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.

Works great
