OXYBLENDNatural Oxygen Cylinder in Portable Can 24 ltr with inbuilt mask 250+ sprays (Pack of 2)

I ordered the oxyblend cans, pack of 2, but received defective items. They arrived without a seal wrapper and the bottles were puffed up with 0 oxygen gas in them. I requested a replacement, but the new product was also defective. While it was sealed, both cans had very low oxygen pressure, and one seemed completely empty and no gas was coming out. I dont know whom to blame here Oxyblend brand or Amazon for this, but it's incredibly frustrating. I've been using this product for a family member's medical needs and have been a regular customer for the past 2 years, and I know now how Oxygen smells or taste like, its pressure for doeses, I know it doesnt have weight but Oxygen not coming out of the can is surely an issue. It seems I can no longer rely on it. I plan to switch to a different brand and will also share this experience in a review.

It's a scam folks. I ordered for my late grandma, who obviously could not use it, as both the cans were empty
