OXYZONE Natural Oxygen 12 Litres in Portable Can | First Aid Essential | Revitalizes | Enhance Physical Wellness | 12 L | 250 Puff

The product met my expectations and works as described. Quality is good, and it feels durable. Setup/use was straightforward, and it performs well for its intended purpose. Overall, I'm satisfied with the purchase and would recommend it to others.

Have been using it for years for asthmatic. The contents and its weight or volume cannot be assessed and i have found at times found the number of puff in some cans is subsequently less

Tho it comes sealed, can is practically empty, with a very very weak air flow to zero air flow despite multiple pumps, so it’s a very unreliable and risky purchase in times of emergency! No use at all! I purchased 2 and had to return one! Very disappointing and untrustworthy brand!

This is not a highly pressurized can which has liquid oxygen in it. Since the oxygen is in gas form in the can there is very little usable oxygen. Better to go with a heavy metal oxygen which can withstand higher pressures and store oxygen in liquid form. Even for high altitudes this light weight can concept is unlikely to be any real use. It would be like giving somebody on a desert trek the equvalent of 10 ml water. That 10 ml can also make the difference and be a life saver but that would be stretching things too far.

Good Product at appropriate price
