Hey phil im a huge fan of your reviews. Very in-depth review.
Im no electronic expert but maybe someone on here can help me out.....but doesn't Frequency and Time And Vpeak play a role to determine the RMS Voltage with the SVR???????
This may help explain why your seeing those Voltage readings.
I hope they work out the bugs like you mentioned. If they do i will be ordering one for sure.

It'd be a great $45 dollar device.. $89 they are crazy.. You can get a LavaTube for less.. I expect the price of these to drop to $60 in a few weeks.. Then probably $50..
I'd jump in for $45 tho.. Seems fair, especially since the Chinese price is around 20 bucks..

Everyone should check out what the vapinggreek Dimitius found out about this device..it turns out this is not a unique USA made device but rather a Chinese made device that is more or less a copy of another device....it was enough info for me to determine I dont want to do business with this outfit.
Wow, now could that be anymore detailed! I think it was a great and honest review. Good job PB.
Not sure these semi vary voltage's are going to last a long time on the market at this price. I just can't see a new vapor getting this over an ego or smaller (or cheaper) device, or a more informed shopper just getting a true variable voltage device (if that is something they want). That price is a bit insane, a year ago it would be competitive but today there are several options for less, or do more.
Price and function wise it just occupies a strange place in the world of devices.
(second time I have posted this, the first time I stuck it in another of the maestro's reviews, lets see if it sticks)

Wow! Such an interesting, honest and informative review - the whole 40 minutes just flew by!
Nice looking device, for sure, but why not shell out and extra $20 and get an Infinity for true variable voltage? As Goldenkobold said, I can't see this class of device lasting at this price point.
PWM may be just a selling point for increased battery life - if, indeed, the increase is significant - but if the cost-benefit to that selling point doesn't make it worthwhile then I can't see this idea taking off unless the price of PWM devices falls.

The only REAL catchy thing (personally speaking) is the waterproof factor NOW, with that said, it voids the warranty and it doesn't float... It's a beautiful device and you can see the intricate work that has gone into it. Very classy and VERY sleek. 
As always a great review!
I like this. I've been wanting to get a VV for a while now, but so many seemed so bulky, and I really didn't want to deal with so many choices of voltage. This kind of finds a middle spot for those of us who want some perks of vv, without all the other hassles that come with it.
I may just get this..

It's basically a pulse-width modulated sawtooth device. Basically, instead of a DC voltage, it shoots pulses, giving you an average voltage of 3.9V or whatever it is tuned for. Basically the pulses help with temperature and power draw. You draw less lower due to the pulsing waveform, since the battery isnt engaged all the time, giving you an average voltage of 0 (it goes from -1 to 1 from what I gather on the site), which means you won't really be able to tell what max voltage it is putting out on a regular multimeter. Also, it lets the heating coil of your atty/carto cool for a split second while the voltage swings downward, probably giving you a bit more longevity with the coils. This may not be true, since the temperature shock of heating and reheating of any type of electrical devices is what causes most damage. However, I suspect that the coil won't really cool down much between pulses, giving it a nice steady temp throughout the use of it. Compared to a DC device, this is I guess their main design principle, since when you press down on a "regular" mod, the coil just gets hotter and hotter until it burns out (if you have no juice and just hold the button down), whereas this mod lets the heater get to a steady-state temperature. I am not affiliated with Akston or anything, I am just an electrical engineer so I am speaking from what I saw on the website and forming general assumptions based on what I currently know.
EDIT: Woops, just saw the video you posted. Nice work on the Oscope! So I guess it uses a square wave with (eyballing) about a 60% duty cycle. It doesnt go from -1 to 1, but 0 to 1 (1 being the max voltage), which makes more sense. I just was looking at the site, and they had a pic of a sawtooth wave. Anyways, pretty interesting device, but I am a bit disappointed that it doesnt have any feedback to control the duty cycle (percentage of time the unit is firing vs off) or voltage, which is kinda lame. I assumed it was a bit smarter. The reason for the not-so-increased battery life is just due to powering the circuitry in addition to providing power to the load. Interesting device, but for the price, I would expect more electrical fanciness since they are going in that direction. Thanks for the review PB!
