There IS truth to what you say but....
I was happy with my Kayfuns and had no issues there. It took 3 visits to The Vape Shop and them telling me I should at least try the Kabuki before I actually did. All my Kayfuns are now boxed up and I have a herd of Kabuki's in service. Sometimes, change is good...
But you didn't change for the sake of change... you had the opportunity to try the thing before buying it. You were able to determine that for your purposes it would be an actual improvement and not a gamble.
But you've also got to consider other factors. It'll have your build & materials quality, you can make it have larger channels for higher wattage/higher vg juice. Kayfuns are out of date due to it being near useless over 15w or anything higher than 50vg due to its microscopic juice channel size and an airflow similar to sucking through a coffee stirrer.
Not to mention it'll have your air flow engineering, a P3 connection, and the Zen branding which also assumes flawless looks.
Believe me, it WILL sell. There are plenty of people who never use sub-ohm tank/pre-built coil heads like me.
There was also a time when plenty of people never vaped. This industry is a revolution that busted the status quot wide open.
And I'm
absolutely sure it would sell if I made it. It would also be a step backwards in my goal to obsolete rebuilding in the mainstream vaping industry. At the end of the day, a new product will either be in keeping with, or working against my goals as a product designer.
My over-arching goal is
to make combustible tobacco obsolete... It may not happen in my lifetime, and in all honesty I cannot do it alone, not by a long shot. MANY designers and product developers need to get on the same page. In order to do that vaping has to become easier and more mainstream. For vaping to become more mainstream the products have to be easier to use so more people will let go of combustion and pick up vaping.
I took on the challenge of trying to make a device that uses a drop-in coil that could challenge the rebuildable tanks on the market, and every day I get messages from people that say they have left their rebuildables in the desk drawer in favor of the flavor and convenience of the Kabuki. Mission accomplished. But that is only step one in a laundry list of things that need to be done to accomplish my goals.
My next move is to take that concept and make it even better, and even easier to use... so even more people can experience it. Each step will take me further and further away from rebuildables, not heading back. One day there will be a generation of vapers that start out on the kabuki or something similar, or even better... and rebuilding will be just a faint memory of what "the old guard" used to do.
So yeah, If I introduced a rebuildable at this stage, it would sell. I actually have a bigger agenda than selling a bunch of tanks. My goal is to keep advancing so a whole lot more lives can be saved.
