Don’t get the alien. Please don’t get the alien. I have one and it was dead like 4 months after purchase. They are cheaply made and there are so many more mods out there in that price range that aren’t total crap. I have lung issues myself, a boatload of scarring from mrsa pneumonia. I started out on the little clearomizer pens two years ago and I’ve upgraded other the course of time. I honestly didn’t start really enjoying vaping until I started subohming. The flavor and vapor density are so much better. You can also dial down the nic in your juice. I can’t Vape above 3mg in my tanks without feeling like I’m going to die.
