Out of the box, I was happy with Kanger protank 2's. Now with that being said, I got a Kayfun lite clone. I didn't even finish the first tank before buying a sedcond one. Building coils really is not difficult at all. I started personally rebuilding my Kanger heads. Thatss a PITA for sure, but after a few it's pretty easy as well. Moved to the Kayfun clone and found I should have done it months ago. So much more room and the experience is just unmatched to me up to this point. Depending on what part of SC your in There's a shop I like alot that helps people and they even hold classes for building.
