The V5 shows two lines of information when fired because it has different firmware than that used for V3. The OLED display itself is probably the same.
Voltage regulation for sigelei Zmax V3 and V5 is among the most accurate in the business with battery voltage from 3.3V to 4.2V at all power levels. The 33.3 Hz chip can produce a faint sound from the atomizer or the device depending on power used, battery voltage and atomizer type. This sound has no effect on vapor quality as far as I can tell. 33.3 Hz chips are also used in Vamo, SVD and countless other devices.
PWM circuits of one kind or another are used in all VV and VV/VW APVs. Regardless of frequency used these devices do not make pulsed vapor. Vapor produced by atomizers using power supplied by PWM waft from the coil in an uninterrupted stream. The vapor will not come out looking like a rippled cloud or smoke signals.
I agree completely; while it was a little disconcerting at first, when I first heard that 'stuttering' sound, it really has no effect whatever on the vape itself. Whether I use one of my vv3s (which has no stutter whatever), or the Sigelei, the quality of the vape is really determined, at least 99.9%, by the atomizer, not by what's powering it or what sounds it may or may not make. But, many of us keep saying that, and quite a few seem convinced that the stuttering sound they hear causes some difference in the vape (pure imagination!).

Would the heat from a heating element run on DC be superior to heat produced by a heating element run on AC at 60 Hz? What about the light from a DC bulb v. AC bulb? I guess that if one wants "smoother" heat or light DC is the way to go.Its not imagination, voltage regulation is a complex field..The new DNA, the old Provari have surperior voltage regulation schemes, results smoother vape. I know I simplified EE101 but that's the just of it.

I'll agree, that's a bad analogy. I maintain that a heated coil is going to produce a fairly consistent amount of heat whether it heated by unpulsed DC from a battery (like with a mech) or pulsed DC from PWM. I don't believe that difference is enough to be noticeable when vapor production is dependent upon coil heat. Heated coils take time to cool down and the pulse rates used by PWM rigs aren't long enough to produce pulsing in vapor production. If PWM is detrimental to vapor production the best vaping possible is the pure DC mech followed by higher frequency PWM as a second choice and 33.3 Hz rigs at the bottom of the heap.
When I put on some music wearing closed Sennheiser HD 280 headphones I don't hear any sound from the Sigelei and the vapor is just as good as that from my non-PWM rig at the same power with the same atomizer.
This is what I meant by my comment "pure imagination" -- when you can HEAR something, your mind will go to great lengths to inform you that what you are hearing is *significant*, even when it's not -- it's what the mind does, attempt to find meaning even when there is none. Maybe instead of "imagination," a better term would be "psychosomatic" -- a difference is *perceived* even when it is not really there.
When I've just built a coil, usually for one of my kayfun clones, I generally test it, and then heat it in order to compress it, right on my sigelei. When the coil heats to red, there is NO pulse that can be discerned by the human eye -- it stays solid red till a few seconds after you let go the button. If the human eye can't discern it, I really doubt that any other human sense would be able to either -- but because that pulse can sometimes be *heard*, the brain busily informs you that hey, something is happening, can't you tell? And since your ears can sometimes clearly hear it, then the rest of your brain figures it discerns something too.
It's somewhat on the order of these people who come up with all sorts of interesting reasons why they just can't vape -- their brains, addicted to cigarettes, are busily supplying them those reasons, in order to rationalize something it really wants -- to continue enjoying cigarettes. Brains are truly nefarious at times.

This is one of the most sensible posts I have ever read on ECF. My phone doesnt show a like button on the mobile version of ECF but when I get home today I'll like it twice, if possible.
Andria, don't know if you've seen this, but here ya go, everything you've always wanted to know: http://www.e-cigarette-forum.com/forum/health-safety-e-smoking/3305-list-symptoms-when-quitting-tobacco-changing-ecigarette.html
I vape 82% VG with 18% distilled water, drink over 1 gallon of water a day, and still suffer from dehydration. It's not extreme dehydration with all that water consumption but it's still there. The tiniest bit of a headache is my first sign. VG is also very dehydrating.
Hope things better for you soon AndriaD. I had some problems with edema at the ankles and lower legs. It's a pain. My case was caused by inactivity and too much time spent sitting after breaking a leg.
I was checking out Varitube today and noticed that their flat top Sigelei V3 is out of stock. This is the first time I've seen that happen with this vendor. They say the flat tops will be back in stock this week.
