Good product

Very help & useful product to athletes

Bought 4 pack of Large Size. Delivered before expected delivery date which was good. BUT, got only approximately 20 puffs out of first can! Claim is 200? Did not notice any difference. Will see how rest of cans go.

I use the oxygen product for my wife when she felt her chest tightness. The first one and the second one are ok though they were used out quickly. When we used the 3rd one, it was totally empty without any oxygen or air stuffing inside. I dropped a complaint before was going to buy six more, but nothing came to me. Feeling so bad about the seller and the platform. That's why I quit form so-called "primer member" 2 days before.
