Took your survey, MBA grad and like many of us ECF snobs I don't know how much of a "typical" ecig user I am, in that I have graduated from V2 in the start to advanced devices including the Provari. The cig look alikes are what get the marketing dollars and were what probably introduced the majority of us to ecig technology.
I am curious as to what a random sampling of ecig users would show, if they stick with the cig-sized, move on to eGos, or what percent really do purchase advanced devices. And at what point (for example, after how many months) do they make these purchases? Companies want to know this kind of info, in deciding what products to make, how to market them, at what price point, and through what channels (which are the 4 Ps). I notice that even V2 has a beta clearomizer type device; ecig users are demanding more, and becoming more sophisticated. Perhaps what is our "niche" here at ECF is becoming more mainstream.
Of all the cig look-alikes, Blu at least uses 510s and Johnson Creek juices, and there are a lot of people on ECF who did well enough on Blus that they quit smoking, but were just looking for more in an ecig. I read the other brands like NJOY mentioned less. I'm sure now that Big Tobacco owns Blu, they will be pouring quite a bit into market research to understand the segment better!
I tried not to read too much into the purpose of your marketing project however and answered your questions honestly as they applied to me. Good luck with the project, I remember writing many on Survey Monkey and it can be like pulling teeth getting enough responses!
