Ill tell you guys though I found out yesterday about the new Kanger coils BUT they are the ones with the 2 hole,I guess these were made in between the outside wick and teh one hole,I put them in my regular Areotank and WOW they are working awesome,never had such vapor from any tank on my MVP2,and Ive tried alot including Iclear30,mini Aero,that junk nautilus,what junk that thing is,worked awesome first week til I changed coils,it cant just be teh coils cuz NONE work.So just saying teh intermediate dual hole Kanger coils are very good,at least my experience.
