Wow! I actually like the design of this. Making me want to put off my buzz pro purchase for the envy instead
I would like to suggest somethings as someone who still likes to use ego type stuff.
Top Cap:
With the increasing popularity of carto tanks, i would suggest a top cap OPTION that is a bit more flat with a small catch cup and the connection sticking up a millimeter or 2 at most (a little leeway to fit tanks). I think it would catch people's eye a bit more because they will have a small pv but also have the option of using tanks without the little stem between the tank and the PV itself (more flush to the pv).
Diameter of Envy:
I could understand the market being more towards the ego users, but i dont think going thinner than the ipro is necessarily needed. I've been with ECF for a few months and i noticed quite a bit of inquiries about the e-power when it first came out. It became a big interest with ego users (including myself back then) because it was small in diameter but also had replaceable batteries. From what i've read on a site, the diameter is 17mm for the 14650 version and i'd expect the 18650 version to be 21mm in diameter (about a mm bigger than the buzz pro). Both were a well priced option until the switch/button problem plaged the name of the device. I was doing a bit of calculating and i noticed that the tube itself on the ipro is about 3mm wider than the battery. I dont own the buzz pro or the ipro right now but i would imagine the thickness of the tube walls are 1-2mm with a tiny gap between the wall and the batts. Since you intend to use the 16340s, I would suggest bumping up the size just a tad to 0.75" (approx 19 mm) so that the tube can be thick enough to maintain the durability of the envy as with the current design and also have a tiny gap between the batts and the walls in the event of battery failure, the gases can bypass the sides of the batteries and down the bottom (also room for the battery to swell up during the failure). Another plus side to bumping up to 0.75" is the fact that 3ML carto tanks are 0.75" in diameter (at least for my tank) so it would match up really well to the tank (kinda like the tank that was increased in diameter to match up to the silver bullet). It would make the pv a tad more sleeker since u would be able to lay it on fully on it's side if needed without it being lifted by the tank (or lifted less). If the e-power got a good amount of attention despite it's size being pretty much the same size as the ipro, I would think maintaining the size of the ipro or the slight widening wouldn't be too bad (still would be smaller than the buzz pro and the 18650 e-power by a few millimeters).
HIT control placement:
This is more of public opinion but i thought i would mention it. I noticed on the design picture that the placement of the HIT control is just like the buzz pro. I think that the HIT control should be placed on the opposite side of the button just like the ipro. IMO i think the HIT control being that close to the button makes it look too busy in that section and placing it like how it is on the Ipro would keep the pv looking cleaner instead of having that one spot of busy-ness on a clean looking mod.
I can't really say that I'm speaking for the ego users but I figured I would give a few suggestions that I feel would better it. I think of it as like an e-power mod but built a million times better and with legit VV!
