So I was really skeptical at first, but after receiving my chill, this vaporizer is seriously from the future. I threw the freezable tube in the freezer for an hour and loaded up some dabs. I am a veteran when it comes to smoking but most dab vapes make me cough still. I ripped through a fully loaded concentrate coil and didn't cough once. The freezable tube only last for a few hits but by the time you are done you don't need to smoke anymore.
