I dont like the Blanket Concept of saying that Cartomizers burn their filling. Just like its not right to say that they dont.
There are a variety of e-Cigs out there. Some use Higher voltages than others. Some are Manual and some are Automatic.
There is also a huge range of the way people vape them. Some take One hit and dont take another for a minute or two. Some people have their PV duct tapped to their hand and Chain vape. And some will only refill when the carto does produce vapor at all while others refill constantly. Carto dripping without an end cap or as I have heard it called, Tail Piping.
And another huge factor is that cartos many times are not branded. If I order from off the same web site that I got my cartos from 3 weeks ago, is there any guarantee I will get the same ones made by the same manufacture? How can I even tell someone which type of carto I use?
So it all boils down to this for Me.
I have done a Carto-ectomy on every carto that I have retired. Some have just quit and some just dont produce enough vapor for my taste any more. When I examine the inners of each carto I have never found any burned holes in any of the filling material.
What I have found in the cartos is a patch of brown gunk which looks like Caramelized Sugar. And this is much apparent from cartos that had Sweet or Creamy flavors in it. Ie: Caramel Apple, Mocha Coffee, Maple Raspberry, etc.
Maybe it is the way I vape them and or the Frequency at which I refill them but for me, using a 510 & eGo, Im not getting any burned plastic. Period. End of Story.
Let me be Very Clear on this. Saying that My cartos are Not burning is Not Based on something I have read that Someone Else has written. It is based on about 30 Carto-ectomies of 3 different 510 cartomizers brands.
Can a Cartomizer burn the filling material. I really dont see why it couldnt. Using High Voltage, Vaping it when it is low on Juice, Vaping harder to wick juices like pure VG, Chain vaping with a short period of time between hits, cheap cartomizers. Perhaps all of the above?
The long and the short of it is they work Extremely well for me and they cost a Fraction of what I was spending on atomizers. And there is no need to jump thru all those hoops and do all those Silly mods only to get so-so results and poor life out of a cart.
Will they work as well for you as they worked for me. Will you like them as Much or Better than your carts. No way of telling. But it would seem that the average person can afford a 5 pack of cartos and try them for Themselves.
If you like them, Great. They are much easier and last much longer and are cheaper than carts/atomizers. If you dont like them, well thats Great to. Because you didnt spend a ton of money on them and now you know.
