I've not heard this. Clearly, to a new vaper, too much vapour could cause problems.
I don't find them "hot"... which is a fair test (i.m.o.) as I mostly vape on normal kit anyway.
Hmmm, I'll have to reconsider then, but at the moment, the eXpromizer is out of stock in US from what I can tell.Out of mine, a Taifun GT, Kayfun 3.1 and a Kayfun Lite plus and my newest, the Expromiser, it's hands down the expromiser. Easiest to build on and wick, best flavor and overall best vaping experience.
Kayfun-style RBA (tank on top)
Genesis-style RBA (tank on bottom)
IGO-W drip atomizerAnother vote for the KFL+. I've had mine for about two months (authentic KFL+). Only issue I've had was some leaking from the air hole. Initially I thought it was an o-ring problem, but a buddy showed me that one of the tank rings was cross-threaded, allowing an air leak into the vacuum chamber. The KFL+ has extremely fine threading, so it is easy to cross-thread the parts. I run a single 1.3 ohm microcoil which can be used on a Provari, MVP, or mechanical mod. Extremely cool smooth flavorful vapor. Best tank I've ever owned. Take that back, best juice delivery device I've ever owned, period. Highly recommended.
