For the past weeks I have been searching for the perfect, all natural vaporizer. A vaporizer that does not contain plastic, glue, and other toxic materials. For hours I searched online, scouring through all the forums, online shops, and reviews. After a couple days I happened to stumble upon "the Ubie". To my suprise, it looked like the perfect vaporizer, in that it was seemingly made only from glass, and affordable too. I decided to order the Ubie after reading a mix of reviews so I could receive the ubie experience first hand. Upon picking up the Ubie for the first time, I realized that it wasn't made completely from glass. In fact, the mouth piece is half silicon and most likely attached with glue. If the Ubie gets too hot, it could possibly heat up the silicon too, strengthening the the release of silicon into the air. I reasoned that I could still take hits without the mouth piece firmly attached. Nevertheless, it was a strike against the Ubie manufacturer which claims that it's made from only Pyrex glass. Now for the hit. Online I have read several different methods for how to use the Ubie vaporizer. On The Ubie website, it instructs you to hold a lighter just 2 cm below the tip. While this method is supposed to heat the air for you to inhale, it actually is quite unfeasible to perform. First, the air that you heat up, is rising very quickly. In order for you to capture that air, you would have to suck in incredibly fast. Yet the holes are too small for this maneuver to work. Instead, the Ubie vaporizer works more like a conduction vaporizer, as opposed to a convection vaporizer. This means that instead of heating the air, the lighter actually ends up heating the glass which then heats the herb inside. This process doesn't "evenly" heat the herb like the website claims, but actually ends up uncontrollably stinging the contents. Somewhere in between it's original state and burning, vaporizing does occur, but you are left with charcoal'd herb. If I had to give this vaporizer a rating, I give it 2 out of 10. The two points are for it's attempt at making an all glass vaporizer pipe with a unique design. However, this vaporizer fails to meet the overall objective of cleanly vaporizing. Also, once dirty, it's a pain in the ass to clean. I wouldn't recommend to anyone to try or buy this vaporizer. In the end, all you are left with a charcoal'd pipe that is evidence you just burned a hole in your pocket.
