Look someone new needs to find their nic level which is a big problem for some people. It was for me. They need to find their juice. They need to figure out the difference between cartos and atomizers and which they prefer. They need to learn what a drip tip is and when to use it. They need to determine whether vaping's for them period. While they're doing that, they don't need to be dealing with varying the voltage on top of everything else. That's best left for another day. If they get an ego class device and learn what they like, then they have a basis for working with VV. The ego will be fine for a backup.
VV won't feed your juice better. VV will not make vaping less hassle. It only varies the voltage. I will even say that someone that hasn't tried varying the resistance first shouldn't even think about VV. Varying the resistance will give them an idea what VV can do and a basis for deciding whether it's something they would like.
With an e-Power or just about any other 3.7V device, their choices are going to be either a 1.5 ohm single coil carto, or a 2.0 ohm single coil carto IMO. A faster-draining battery like a kGo/Joyetech will let you get a decent, but not great vape on a 1.5 ohm dual coil. A VV will let you try any combination of resistances or number of coils, and will actually allow you to taste juices as they're meant to be tasted, instead of at wattages less than what release their full flavor.
Using a variable voltage device is not complicated. Buying one is not complicated. Selling one is not complicated. I do not understand why everyone is making such a big deal out of the supposed complexity involved in using them.
My friend Dan was just here, with his new ProVari. He agrees with me that it makes excellent sense to statrt with a device that will give you the best vape you can get, right from the start, and then add a second, stealthier PV if you want one. To me, it is a slam dunk no-brainer. Juice is fairly expensive, up to $3 a day for a heavy, non-DIY vaper. That is $1,000 a year for juice. Why not vape it with a superior device that will let you fully enjoy it?
My backups have backups but, I have a eyeglasses sized case that is nearby wherever I go. It has a couple ego pass throughs, a cartomizer, a drip tip, an atomizer, and a charge cord because at work I can charge it off the computer. Most of the time when I use it, it's because I left my extra batts for the REO mini at home. That case is always nearby. Even if the worst happens and I lose my main vape completely, I'll be able to assemble something to get me through the day. Another not well appreciated property of egos is that they are relatively small.
First off, we're talking about someone that has almost no experience. They aren't likely to know that one way or the other about selling it. However, that's only one side. VV still makes things more complicated and they don't need that. An ego style kit will serve well as a backup if and when they decide to go VV. However, most people probably won't decide to go VV.
IMO, what they don't need is to be screwing around with devices that won't even properly power most of the available attachments available, including high-res cartos that deliver the best performance. Why are you guys so anxious to deprive beginners of a first-rate vape? Most people really are not so stupid that they can't understand the basics as I tried to explain them in the "TMI" thread,
http://www.e-cigarette-forum.com/forum/new-members-forum/291542-way-too-much-info.htmlor or can't figure out how to sell something that didn't work out for them. That said, I can't quite imagine what anyone who wants to quit smoking would find not to like about a Smoktech VMax running Boge 2.0 - 3.0 single coil Boges in a DCT tank. I just really can't.
And lastly - I am so glad I did not get the ProVari. It will not - repeat, will not - run a 1.5ohm dual coil cartomizer that happened to come in at 1.4, which put it at just over its 3.5 amp limit. The VMax will power anything out there, and I like the looks and feel of it better to boot. Add to that the raw battery power advantage that the VMax has, and it's game, set, and match.
