I shall dub this new concept The Hybrid Tank System.
Here is Kangers answer to Aspires new Atlantis tank. If everything works well - Kanger may win this round. Meet the Subtank. Much like the Atlantis by Aspire - this uses .5 ohm replaceable heads. Where it absolutely destroys the Atlantis is the ability to use a new RBA head. With that kind of choice - this will allow fill-n-vape users and rebuilders to use this system.
This concept seems simple but its somewhat revolutionary. Unless you rebuilt your protank heads its been one or the other when it came to these tanks. This has been built from the ground up to support all different vape styles.
IF this works well - I'm sure we will be seeing a lot more of this style system.
My minions - go forth and spread this post. :)
