Simple but very effective locking mechanism that cant move or get unscrewed and fire your esterigon by accident
Extremely easy assembling-disassembling procedure
Side venting holes for real safety (your esterigon will not be a rocket inside your mouth in case of an explosion) and away from your face
It sits in vertical position
It doesnt roll on surfaces
Ability to accept all batteries with different tubes
Air control that totally seals air
Automatically adjustable center post to accept all atomizers
New style connector that doesnt allow liquid to escape to your battery
4 cuts on connector to avoid damage on it and increase air pass
New spring loaded application that maximize the electrical conductivity (bended spring, strong spring, spring with fat base that is kept by a case that makes spring and case behave like one piece, very small tolerance between case and moving pin so spring doesnt play a major role in conductivity, spring that sits inside the moving pin so it touches moving pin with its top and side surfaces at the same time)
Rounded contacts on posts that button touch to avoid any kind of misfires
Shined contacts to maximize electrical conductivity
Contacts, button and its spring can be removed (when you want to clean or replace them) with a simple pull, using only your fingers.
It takes 18xxx batteries but its still at 21mm external diameter
There is no plating anywhere on esterigon, something that is reducing the electrical conductivity and make contacts look bad after sometime
Its all shined to avoid dirt and rust. Also it will not get shined to only where you put your fingers after some time because its already shined
Its contacts need cleaning very rare because you can turn the contacts to a new position everytime you see a reduced electrical conductivity, so you have new contacts every time
There is no gap anywhere while you vape. Its like one solid tube
Ability to accept GG electronics on it
