Okay so I postponed writing my review for a long while, as this vape was very low priority for me, at least the clone that I got.
So I have the IVEID version with the short straight mouthpiece. I think I got it from DHgate for very cheap. At first I was happily surprised to see that the glass top has a built-in splatter guard, so that contrasted to what was said previously about eating globs... but then upon closer inspection, I realized I only got a clone and not the real deal.
I guess the top glass is okay, the heater/cup assembly looked okay too. But when I disassembled it, I noticed the silicone joint at the bottom of the heater, and I bloody hate silicone. I also noticed that the IVEID is a bottom airflow atty (there are 4 holes in the 510 base, which leads to a space below the heater. Then the heater base also has a few holes.... then the air goes... nowhere!
If you take the heater cup and try to blow into it, nothing escapes by the bottom... and since the top glass has no holes, just the mouthpiece... well it appears, unless I'm completely crazy that air doesn't enter the device anywhere in fact. You just create a vacuum when you draw, then air enters back through the mouthpiece.
This is weird but the good aspect is that the silicone joint is not really in the vapor path... But that whole heater and the way it's built under.. that doesn't instill confidence. I'm sure that if you overheat you could melt that silicone part.
I tested the device nonetheless and had a hard time getting TC to work. I found a setting, Nickel or derived if I recall correctly, that kinda worked. It overshooted a lot at first and made the coil glow bright, but when I released the trigger then retriggered shortly afterwards, it managed to more or less stabilize.
I got some good vapor but it was clear that the regulation was not very precise at all, taste was spoiled quite fast...
So in the end, I still prefer the VapeDynamics CeraWax atty, but it's not a panacea either. My concentrates use being quite low it's good enough for me, but I'm sure it would leave a lot of you wanting for more...
