i agree with you, it may be a fad, especially in souther California but there is reason to it. thats fine, u state ohms law, thats a very basic and correct way of looking at dc current voltagexamps=watts, and all the other ways you can derive the same equation. However, its also true that signifiant factor in vapor production is wire temperature. Wattage to wattage is not comparable at different resistance's and wire gauges. thicker gauges with lower resistances have a lower wire temp, and depending on the juice will produce better flavor. To obtain the similar wattage, u either lower resistance to increase electron flow, or you increase voltage (wither higher resistance coils) to push those e's through a higher resistant wire. Higher voltage is related to higher thermal conductivity and you'll burn juice easier with that higher wire temp. But in the end, like a few others have said, its all preference, i own both a number of "brand name" mechs and clones, an evic, and a vamo that i now use as an ohm meter (hehe). I tell you, besides machining, which is hit or miss, the conductivity of the internal connections of clones, are somewhat lacking, because the alloys they use are inferior (cheap compositional brass with lots of zinc), or its not plated with higher conductive metals like silver or purer copper. But yes, you right they work fine for most. Simply put, my PREFERENCE, are Mech's though. Just thought i'd clarify a few things here. LEts all just vape and be happy.
...no need to get it all cranked up in this post.
but there is nothing wrong with a VAMO... I just sold mine but WILL get another. I am also going to get the Natural mech. mod. I used a vivi and kanger MT3 and EVOD and Protank... but two tanks I used that made me wonder why I bought them is the AGA-T2 and IGO-L. The Protank is great though, but not the same ballpark as the AGA and certainly not the IGO-L.
