This is not legit!
This is some kind of rip off!! I ordered them because these bottles crack. I get them from a legit company and they still crack. However with these there is a way to test if the oxygen is working. I suggest you go to YouTube and look it up. They do not work they do not hold the oxygen the way it should be. If you’re using these you are not getting the amount of oxygen that you should be! I immediately noticed the color was different on the top it’s a brown versus a black. And when I tested it it kept popping showing that the oxygen is not getting through it. I want my money back and nobody that uses oxygen should use these even though they say they’re from the same company as a legit company. Come on Amazon get it together check your stuff out before you sell it. People are talking about life and death here!
