What surprises me most about the iStick's still-unconfirmed but presumed and likely PWM implementation (i.e., using Vavg rather than Vrms for calibration and display) is that the engineers who chose the production specs---whether those engineers were at eLeaf or from a wholesale Chinese hardware manufacturer contracted by eLeaf---would make what many users in the sophisticated segment of the vaping community regard as an obvious mistake or even an egregious misjudgment.
The PWM calibration brouhaha back in 2012 was a big deal here on ECF. Chinese manufacturers of variable voltage APVs who used Vavg received considerable negative feedback from the marketplace and were relatively quick to alter their products. For instance, Smoktech's mid-2012 VMax VV and subsequent upgrade/replacement ZMax v1 VV/VW used Vavg calibration (or mis-calibration, to be more accurate). By the end of 2012, however, makers of the ZMax v2 and newly-released VAMO v1 had amended the programming of their chips to include an extra menu item that allowed users to select either Vavg or Vrms for calibration. By late 2013, most VV/VWs that used PWM had eliminated Vavg calibration altogether.
So, my question for eLeaf becomes: Why did you choose to step backwards two years? What made your development team decide that Vavg was the appropriate calibration for the iStick? Further, at the very least, why didn't you give the end user the choice to select either Vavg or Vrms? I'm presuming, of course, that eLeaf had a reason other than incompetence or being out of touch with the technology and the marketplace.
Anyway, now that I own an iStick and have used it for three days, mostly happily, it strikes me as an odd combination of current chip capabilities (higher wattage) with antiquated programming (unsmoothed PWM with Vavg calibration that makes lower wattages inaccurate in terms of real-world vaping), especially so since the size, build quality, and ergonomics are so well-designed and implemented. Compared to the new 35-watt VAMO or other more expensive high-wattage boxes, I'd much rather use the diminutive iStick, but this Vavg calibration thing leaves me scratching my head.
Please understand: I don't feel deceived or ripped off. I won't return my iStick and will continue using it, since I'm not a primarily low-wattage vaper. It's a cool little unit that gives me most of what I wanted, but I won't buy another until this issue is resolved or at least addressed by eLeaf.
I'm doing well thank you.
I deleted the singles when I made the one pic 
guess I'll know better next time 
Zooker ! I've missed you so ! Thank you Babes ! 
Thank you though ♥
