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

This product does the job for me. I highly recommend it and have used it several times and will continue to use.. I had a slight issue and I have to say the seller was amazing. Every issue was resolved less than 24 hours. Seller was extremely professional replaced my product. I cannot express the gratitude I have because it usually takes a while for anybody to even respond. Never mind getting the issue resolved in less than 24 hours. Thank you for your professional and quick response..

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.

The larger packs are a better deal

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.
