The only thing that matters is does the rig satisfy you and is it cheap enough.
In that vein what I want is a replacement therapy for smoking.
That means all I want is convenience, good rich satisfying vapor, enough nicotine (heading toward ZERO which everyone should do just because you can) and all that for nothing. Well not nothing obviously but as close to nothing as I can get at my skill level.
But most of all I want it to be SAFE.
Safe for me and for those around me and any grandkids that come over, pet monkeys and the like, etc.
So after months of using the eGo 650 with the Kangertech T2 plastic Clearomizers I ran into e-juice that eats the damned plastic!
HORRIBLE! And not at all good for anybody I am sure.
So now I test all juices on an old CD before ever putting them in my tanks. One drop on the burnable side (same plastic as T2s are) and if they wipe clean after a day they are golden.
If they eat plastic, discolor it, smear it, make it cloudy, or outright MELT it like Amaretto did, I throw them out.
I also only do business with folks the TELL me when a juice will eat plastic (those juices should be banned imho).
I also switched to the new eGo-C Twists 900mah and Kangertech Pro-Tank because it is Pyrex (heavy glass) very well made and so far with the twist every juice comes across as warm, rich, and satisfying. I still throw out plastic eating CRAP that has to be poison to human lung tissue.
I also now DIY my own juice and calculate that vaping very heavily, even if I have to replace my rigs (I have two in rotation) twice a year, I can do it all for less than $400.
$400 dollars divided by 365 days is less than $1.10 a day.
Those are real numbers.
And they depend on me not fussing around buying 48 different products testing them out when I already have met my personal goals.
But I went into Vaping with goals not just a pleasure persuasion.
Some are all about fiddling around and whatnot.
I rather read a good book.
The Pro-tank is awesome but it makes my rig look like an RPG or some sort of weapon.
I would prefer a pyres version of the T2 and would then be all set.
But to each there own yuh know?
Good luck and cheers!
