I didn't a decent amount of money, but one of these Disposable vape pens I got just doesn't work. Charged it, or tried to, for hours. Still no luck. One vape works great though, so I know I'm not using these o other two duds wrong or incorrectly. They feel like maybe they're just cheap products. But, I don't know that for sure; but what I do know is that for what I paid, I shouldn't have to try and try and try to get around $50 worth of my ordered merchandise to work only to see it fail. Over and over. And then give up and use the other stuff I got. And, a second vape pen I bought the worked for about a minute, then wouldn't work. I thought that maybe I need to charge it some more and so I plugged it in to the USB charger and none of these things light up when you plug them in or anything but I used a couple of different chargers that I know work for phones, but that second pen doesn't work either now! ☹️ I feel like I threw money in the trash, I won't be buying this stuff again. I thought it was getting a deal, but not really, since only a portion of my large order is usable . Not happy.
