MyFreedomSmokes.com has the X-Pure RDA on sale for $14. It was originally $29.95 (when I bought mine). I love mine and I'm going to buy at 2nd one. It is my favorite dripper. It has a nice deck that's ceramic, and produces tons of vapor. I also saw someone post that she can build it at higher resistance. I'm going to try it when my coil needs replacing to build it for use on my devices under 30 watts - where I would use my Nautilus. Oh ya... The air hole is so high, you can overload it with juice, and it doesn't leak out. I love that. And the top and the bottom unscrew rather than only using an o-ring. Love it! Wanted to post a photo, but didn't see how to. Here's the link. It's under "Clearance" or you can do a search at MyFreedomSmokes.com. I buy a lot from this dealer. NO, there's nothing in it for me by posting this. Joya
Here's what it says under "Details". The Xpure is one of the most innovative RDAs available. With a ceramic building deck you can avoid shorts and enjoy a cooler vape.
Airflow is controlled by a triangular screw (special tool for adjustment included) that can be twisted to allow more or less airflow.
The entire RDA is made of brushed steel and ceramic for a very durable and easy to clean vaping experience.
Simple 3 post design allows single or dual coils.
