Stick to experienced vapor reviews/commentary. Unfortunately, its not a paying job for some of these people, and some choose to say less and some nothing at all. Stupidity generally isnt success either, unless your Daniel Dennett or Sam Harris, it usually doesnt work.
All RTA's can leak too. And some RTA's are finicky. ie (Aqua slightly more finicky then Kayfun despite all the Aqua love.) The trick is too buy ones (clones especially) which do not leak based upon manufacturer quality. If you search through the threads at ECF, there are recommends on high quality clones. <<< The Tobecco Aqua 2 clone comes to mind as a highly rated one, although I dont own one. I find that the dual coil RTA's typically are more finicky, and the more airflow provided by the RTA, (larger airflow channels) the greater the chance of leaking issues occurring. If you have large non adjustable airflow channels, you have to use them, and the draw from the vapor chamber must be spent in vape or leaking can occur, usually from the 1)air intake chamber on a well sealed unit or the 2) drip tip if too much non spent juice gets drawn into the vapor chamber. <<< which is why I typically stay away from those units. <<<<But that certainly isnt cut in stone. I really like the Orchid, but the Orchid is special in its capacity to: 1) draw juice only thru the juice channel when taking a draw without backflow to the airchamber unless flooded due to conditions listed below. 2) not allow juice to seep into the vapor chamber while idle 3) and its ability to reward average wicking. Also with the Orchid you dont have to put wick in the juice channels, which is why I think it is at least the equal of many other dual coil RTA's , although obviously many disagree. <<< Its also one of reasons why I dont bother buying into the the new gizmo's. Also remember that dual coil RTA's by design are intended to burn more ejuice, but if you find atomizers with deep juice channels, the amount of vape produced with single coil RTA's, can be essentially a wash. <<< A really big advantage for non sub ohm vapers.
Other causes of leaking:
1) Improper sealing of unit. (O rings, improper seal from chimney to cap oring, etc.)
2) Battery operating substandard when taking a draw, causes more juice flow without burning up the juice.
3) Improper optimal wicking.
A) which is where some RTA's are finicky and need wicking which is really touchy. <<<< Fogger, at least early versions, is more finicky then the Aqua.
B) the Kayfun is legendary in this regard, allowing a wide range of wicking depending on depth of juice channels.
4) Its commonly reported that leaking can occurr from over wicking, using too big a diameter of coil when wicking. <<<< I dont want to discuss, to me its empty handwringing. ie(I dont wick into the juice well so for me its pointless, but a well designed/sealed RTA should never leak based upon larger diameter coil if the wick is kept above the juice well. <<< Just my opinion. For the obvious reason if the juice cant move to the wick without draw, there will be no juice available to flood the wick. Certainly tho, if someone wicks into the juice well, leaking could occur from over wicking. Just my opinion, and dont want to argue it.) But in the same regard burnt wick taste or dry burn taste can occur from underwicking or not enough juice flow. <<<< More, IMO, a common failing of just bad vape gear or a really crappy wick.
the Kayfun/Orchid Series does have a few non vaping advantages:
1) some Kayfun/Orchid parts are interchangeable but not all of them.
2) Parts and modification to customize Kayfuns are available more then any other atomizer.
3 Rebuilding Kayfuns are about as easy as changing a car tire, if you have the right tools. <<<< Which may be a real big deal if FDA regulations are put into law.
In the end its more important what the user thinks of his own gear, then what someone yarns about it.
