Yea, I've heard those Kayfuns can require some patience.
Yep. I would have to agree. Now the question is do i get a second one, a vaporfi, or wait for the next great tank to come out? I'd love to see the mini with a 5-5.5 ml capacity.....I know there's the original subtank but i've heard there are some significant differences and that the mini is way better. I'd say it's a good predicament to have!
If you like to build it's a no brainer
The sub tank mini and the new sub tank plus are far superior to the og sub tank full in regards to the rba section
