No hot seat there Rob, it was more a rhetorical question.
Au contraire I am not the first one out of the gate to purchase anything. If we look at what is coming out of China these days, it is more or less a fancier version of what has been modded here before e.g the smart carts which all they really are is the Highping mod, but they will hold an extra 4 drops so I have been told.
The eGo T V2 does not require special equipment to tell the difference between the 2 units. The spike diameter of the V2 is quite larger and not a mere tolerance issue. If it is a tolerance issue, then yes their manufacturing specs leave allot to be desired, even for JoyE. When looking down at the spike it is easily noticeable. From a performance stand point the member reported improved wicking, which in turn does make sense.
For JoyE to make the bore larger makes sense, since several folks have wicking issues with the T system. I am only confirming what I physically saw, and have to support the OPs finding. Because it makes sense.
Notwithstanding, the OP stated he got them from 2 different vendors (Canadian), they are branded eGo T and have the same characteristics and look identical as my eGo T atty, with the exception of the larger diameter spike. If per chance someone else is manufacturing and branding the "larger" atties as JoyE products, then that adds to the problem now doesn't it.
My previous observations were never meant to make you look like a fool Rob. I and everyone else do not expect you to open every atty you receive. They are in a sealed package, and should remain sealed. As stated I know where you are getting your gear from and they are indeed reputable. I have no issues with that. I am vaping the smaller spike on my T, which was acquired from your source. As stated I do not wish to debate it here, and hence why certain words are used vice others. e.g source. Nonetheless, the OP has two different eGo T atties and the larger spiked one vapes better.
OTOH several myths were debunked during the meet the other night, through actual trials and certain claims were substantiated as well. Next time I will have to remember to bring my MM and test harness to remove all subjectivity.
