Jaybo was known in this community for his last Wismec RX 200 Mod design which was adopted the reuleaux structure to deliver a good grip feeling on a 3 batteries mod.Now he came up a brand new concept idea with Suck my mod on a tank, named as Wismec Theorem Tank. The deck and coil are placed on the top of this tank to make sure the vapor it produces the purest flavor. The genesis style deck was optimized to a better level, the 3 posts gives vapers different builds choice. The most wonderful thing is if you are into single coil builds, you can put the positive and negative legs of the coil on the same post, no fuss rebuilding experience any more.The Theorem tank comes with 2 airflow control rings for single and dual coil builds, in this way, no need to place the ceramic block when you go for a single coil build, and no need to worry about the airflow amount for dual coil builds.Its top airflow design enables the air to travel to the coil directly, which makes its horizontal coil to produce a clear vapor. The e-liquid fill is quite simple as a dripper for this tank, plug out the top of the tank, and refill it! The Notch-coil it comes with has a clapton wire taste but give the air and juice more channels to mix inside. Plus its glass tube and stainless steel tube option, it would be the tank of this year if we have a award for tanks. Features: Drip Tank Hybrid; Brand-new Notch Coil with Cotton; Optional Atomizer Tube & Airflow Control Rings; Stainless Steel Material & Detachable Structure; Innovative Top Liquid Filling More info：Wismec Theorem RDTA Tank Now Heaven Gifts has this most innovative tank in pre-order.
