I may have an adapter that is "fine" but if the problems inherent in the design/production can make the experience better than "fine" then I want the better design.
Need help from former MFS (MyFreedomSmokes) customers
Has any found a supplier or company that has tobacco e-juice like or very similar to MFS Turbosmog, Tall Paul, or Red Luck?
The 3.7 once you find the flavor you like is a substitute in my eyes for a cigarette. the 5v tastes too much - its the equivalent of smoking extremely strong, extremely flavored cigarettes.

Well..your'e asking for opinions, so heres mine.
I have Several Dura-C's, The Kissbox Extended and the Stick. Numerous others by other suppliers/manufactures too. My favorite of the Janty products that I own is still the Dura-C. You guys really got this one right,(everyone knows it and everyone tries to copy it.) The maunal battery along with it's atomizer is the secret. The reason I stick by it is, that it gives great vapor and throat hit, and comes sized as a reasonably small tube shape PV for out in public and special occasions. Thus it is the one I reccomend to beginners, and others who are looking for the same experience.
I never use the Kissbox anymore because of it's size. It is the size of a very large pen. Tube types are best smaller. We all are previous smokers and in a way still emulating (needing to copy) smoking with our choices of the tubes types. Evidently, it is the ideal size and shape for many of us previous smokers for whatever reason, emotional, physical, etc.. Do you really sell more of the Kissbox over the Dura-C? If so, maybe you are right to want to offer this. Otherwise, I would think that making the Kissbox more bulky is a bad idea. More batteries or not. I think the prototype looks like a large type of butane lighter. The kind you use to light a log stove, gas furnace or fire place. If you made a cover for the batteries I would assume that is what it was. I would not want to vape on it. Also when I look at it, it looks like a tool with prongs, or maybe some kind of electronic tester with two poles to it. Maybe a tuning fork?
Just my opinion, but I would rather see the Dura-C in more classy metal colors. More choices for it. Maybe a classy jewel at the end offered on some too. I would like to see some kind of automatic dripper for it, small and discrete.
So.. my answer to your question is a very big NO! Do not go bigger on any of your products that already exist. Instead, get busy and finish that hookah. I want one for my coffee table to share the vaping experience with family and friends. Why is it not on the site anymore? Inquiring minds want to know what you have done with it.

Check back on page one, where it's been asked and answered. Apparently it's not easy.Have you thought about bringing a twin atomizer e-cig onto the market?
