The SmokTech RSBT (Rebuildable Stainless steel Bottom coil Tank) is the new rebuildable tank atomizer that is great for users to get started with, as well as the advanced user.
The bottom base of the RSBT has adjustable air flow so no more drilling. An isolation ring to make rebuilding atomizers more user friendly. The tank itself is made from durable Pyrex, to prevent cracking.
While I did mention above that this tank is friendlier to beginners, it is still meant for advanced users. Do your research, understand what you are doing. No doing so my result in damage to your device or yourself.
