| I have one of these coming today, via a contest win. I am glad I didn't drop my cash on it after seeing the build quality in your review. I am still looking forward to using it though, shame about the PWM and the mismatched voltage reading/output....pain in the ass for juice reviews. I can pretty much get a Vmax for the same price up here. I DO like that it reads ohms, that is very handy. The LCD is also a + in my books. | |

| Look like a poorly designed POS to me.
Horrible ergonomics and stupid, useless finger slots.
I don't care how careful folks are, liquid will eventually find it's way onto and into the unit. I'm sure this has happened to you on more that one occasion. Not only does it have a seam, the seam also makes a perfect channel for liquid to flow right to the stupidly placed, unsealed top button. No catch cup is a FAIL, especially with this thing. I've seen similar switch problems with the MV RoughStack where the switch gets soaked, a few folks actually added a small o-ring when they replaced their switch to help seal off the switch.
When you look at the Buzz Pro, the original LavaTube and the ProVari, to name a few, they all use PWM. The difference is the design has gone the extra mile and cost to ensure that the output remains fairly flat.
Additional supporting components are carefully chosen to keep output voltage ripple to a bare minimum. Quote: |
The objective is to maintain voltage regulation with minimal current ripple in the inductor to guarantee good transient performance.
| Does that matter when we are only heating a chunk of wire? I think so. These cheesy China designs are still basically always pounding (from your charts) that wire at 6V for part of the time, irregardless of the so-called voltage setting. Sounds far from ideal to me.
I have no definitive proof to offer, but I'm guessing a properly designed circuit that offers a flat output should in fact provide longer life for atties/cartos.
Final verdict?

| Thanks for your input here. I'm beginning to learn more about your comments and the differences between good PWM and bad.
I hope to continue my education in this area and provide it in my reviews. If there's more you can tell me, please PM me! | |

| The real shame is how folks/reviewers have to always explain how the volt reading feels 'hotter' etc.
From your charts I think I've seen some that actually blast the atties at 8V as part of their duty cycles.
But I guess this is that future as these cheap China PVs seem to sprouting like weeds.
Here's another, I don't know if it's been reviewed.  http://www.vaporbreak.com/en/vv350/1...tack-vz6-.html
Typical warning: Quote: |
PLEASE NOTE: It is recommended you start on a low voltage (under 3.7 volts) when you begin to use a high voltage device. Higher voltage use may damage new atomizers or cause the liquid to burn or taste bad.
| About $22 shipped.  Quote:
vv-350 Lavatube alternative otherwise known as the Veri Stack VZ6. A great value cheap mod alternative for variable voltage vaping.
Collect them all to match your mood. It is a great cheap alternative to the Provari or lavatube! Plus the design is simple and so easy to use. Replacement parts are cheap and cost little more than a eGo battery from many other sellers.

About $22 shipped. | So now they're ripping off the already supercheap Varistack? Or is this suposedly a newer version of Varistack?
Now I've herd "decent" things about the Varistack, and thought of picking one up. But to clone a unit that is bargin priced to begin with? To that I say GET A HOBBY!

| That's pretty sweet lookin,but a price tag that low, not in a coop makes me nervous. It would be a great deal if it was solid, but I kinda doubt it.
Any info on amps with this? | |

To that I say GET A HOBBY! | I have no idea what you are trying to say. This a shiny, maybe, SS (which seems to be a noob favorite) PV. WTH does 'ripping off the already supercheap Varistack' mean? It looks nothing like it and the buttons and meter orientation are quite different.
I don't need shiny finger print magnets, but for a few more $ it sure trumps this seamed, plastic toy looking thing, at least in looks and probably durability. 
So this is what you would call a 'clone' of that red thing?
So similar it's hard to tell them apart. Nearly a carbon copy.

Please dear sir, please forgive my ignorance.
NOT!

Please do any recommending of whatever you have in the supplier hype section or ash may be all that is left.... | |
