Ok,
Someone asked me my opinion on the burnt cartomizers and my take on it in pm..and I had been following this thread so I figured I'd just post it here and maybe expand on it some..
My take on the recent discussion of cartos...
First off let me say that they arent my preference on a stock battery...I just in general don't like the flavor on them nor the airflow...I use them on an eGo battery (which is a lower voltage battery than the KR8, so they burn cooler) with an adapter (under the cone) or at 6V
Now about the burning...I think that it comes down to the individual cartos and the user, and luck of the draw..
I think that the burning could be caused by the wire and tube in the inside being off center which can cause a hot point between the wire and the shell which would cause a dry spot and subsequently "bake" that hot spot from both the center and the outside resulting in a burn..I think that the "premium" cartomizers are worse because they have a lower resistance and burn hotter (so they make more vapor)...and this is why the one company changed the airflow on some of their batteries (to hopefully cool them better with increased airflow)...
Now I use the majority of my cartos differently...I vape them at 6V, I take off the cap and o ring first thing, and I use a stainless tip with a wide opening to vape through (so I'm getting more air in there to cool it, just through the other direction), when I open them I always center the wire as best I can (but I also fill them with a syringe and can sort of feel if it goes all wonky and crooked in there(so I poke at my prefilleds too))...this certainly detracts from their easier to use argument..
I've been tearing apart a couple to see since this issue has been being pressed...I've yet to get one that has shown any significant signs of burning...worst has been some dark stains on the inner wraping...and I think I might attribute that more to a wet white fabric touching a metal wire thats been heated and cooled repeatedly and it's just the crud and scale that would otherwise build up much like it does on the coil of any other atomizer...
Do I take an unreasonable # of extra steps..probably..
are other people going to do the same as I do and open em before vaping..probably not..
do I feel safe in my usage of them...reasonably so..
Do I feel that people have a valid concern about the safety of Cartomizers..you betcha..
Are these concerns being unfairly blown off and not adressed...yup
will I continue to use Cartomizers...yeah (because I don't like burning up atties at 6V and the cartos are more throw away in that regard)...but the cartos I use will not be V4L cartos and certainly not premiums (I have high hopes for the vapor9 cartos though..they managed to rase the performance to that of premiums without lowering the resistance (it's actually .1Ω higher))
Further, I'll expound on my tale of that "family" company and concerns being blown off.. the big argument I see constantly is that the KR8 is so much easier and that you don't need to fiddle (read mod) and it works right out of the box, and you don't need to top off as much...well, the trend I see is then advice on how to "fix" airflow issues (ie toothpicks and silicone rings made from carto condoms)..keeping the cartos wet and topped off...removing the cap and vaping through a carto condom with a hole punched through it so it's easier to fill and top off and keep cool on the lips...so if those arent "mods" how the heck do you classify them?...
and as for the fanbase.. hmm if I throw enough free stuff at someone and anything that is faulty I promise to replace (with your next order) people are going to think my customer service is great too...for me I look at it a different way...do I get the correct stuff in a speedy amount of time, how long can I expect things to work properly before I even have to ask about replacement, and communication...then the way the replacement return policy works and is handled, free stuff is last on my list..
And statements that you spend more money than anyone else don't concern me a fig..if I can't get a consistently performing hardware from one week to the next or worry about whether it's a new part or old part or new increased airflow or old airflow or whether my new cartos work on my old PT (or new PT) or not..
At one point there was a user here that had a sig line about that company that stated something along the lines of "they're the walmart of the PV world, the product is crap...but people love them and keep coming back because of their return policy"....I'm starting to see that now.
