Theorem RTA / RDTA by Wismec and Jay Bo Designs

With direct input from the vape community, Wismec and Jay Bo Designs cooked up a new RTA designed for the best flavor in your vape. Check out the new Theorem RTA / RDTA by Wismec and Jay Bo Designs.

Some may call it an RDTA, some may say it is based on Genesis style tanks. What it really is, is a small rebuildable tank that provides awesome flavor and vapor production. Unlike other RTAs, the Theorem's build deck sits above the juice reservoir. This may seem similar to Genesis style tanks, but the Theorem RTA uses cotton instead of mesh to do the wicking. Long cotton wicks will feed juice into your single horizontal or dual vertical coils. Airflow will come from the top and through the back of the coil for cooling and maximizing the flavor of your vape. If you're an advanced vaper that's familiar with building your RDA or RTA, check out the Theorem RTA by Wismec and Jay Bo Designs, and experience a new way of vaping.
