couple things ...
1) it will be tank ready with different types of 510 adapters available
2) even a bit more user friendly/user replaceable parts -- still sealed with floating center post to stop atomizer shorts.
3) built in tank system attachment that seamlessly integrates with the Prodigy V4 (this will likely take another 2-3 months of development -- don't want to release subpar versions)
4) 18650 and its variants -- including a version to use an 18650 with a KICK (we've been in talks with EVOLV)
5) still 100% mechanical
um.... that's about I'll I can release at this point ...
