Easy to USE.....

0/5 🌟Cans are totally empty. Not even a single gram air is present. Pathetic product.

All good

This is most useless product, does not have any utility as Oxygen in any mode. The product has been much hyped for marketing, but the canisters are of no use at all. Moreover some of the canisters are empty. It's just to fool the customer.

This is useless hardly 10 15 full spray ofter that only empty air not recommended at all

Hi,I bought two sets of these for use at high altitudes, hoping for a little extra oxygen. What I got instead was a lesson in frustration.The mask and tube are about as cooperative as a cat at bath time—impossible to fix properly. And even when we did manage to attach them, the O₂ flow was either nonexistent or playing an elaborate game of hide and seek.Multiple people attempted to test these, and the unanimous conclusion was... nothing. No effect, no difference—just a growing sense that we'd been duped. We tried them from 2000m to 4600m, and the only thing we gained was mild irritation (and not from the altitude).Now I have six bottles of useless air, and I'm not even sure how to dispose of them. Maybe I’ll start a modern art installation titled Expectation vs. Reality.

Dislike

I had bought this for my parents as they need oxygen in urgent cases. I used 1 can which gave me 2 short burst of air then it's empty. Not worth the expenses. Better to get a concetrator.
