For some of us, that isn't a choice that is available. I like my attys at 3.4-3.6V. When I set the iStick to the lowest 3.0V, I am getting a device that is actually firing at 4.0V. That kind of margin of error is unacceptable.
If eLeaf wants to create the most encompassing perfect vape to capture as much of the market as possible, they need to fix this ASAP. They have every other piece of the puzzle in place. Form factor, price, battery life, etc. is all spot on.
I am looking forward to the next duel: Innokin MVP 3.0 vs. eLeaf iStick 2.0.
Joyetech has to have something to do with the design and production of this device if they are sending Joyetech reps out to forums to get input about improvements they could make on the device.
The iStick fires hotter than what the setting shows. For many people, this is not an issue, as they can just turn down the power to suit their tastes.
For people like me who like a cooler vape, it becomes a major issue because it can't be set low enough to suit our tastes.
To fully understand the issue, watch pbusardo's video, and when he shows the readings from his oscilloscope, it becomes clear how the settings affect the real world vaping experience.
