As much as I am loving this mod, i have to make a comment about the fire button.
It is way too soft. It is really hard to even hold this mod without accidentally hitting the fire button. If you have your thumb over the fire button, when you raise it to your mouth the weight of the mod causes the button to fire before pressing it.
Dont misunderstand me. The button feels well made as does everything else. There is no rattle or anything.
IMO though, it should be clickier or at least flush with the faceplate or something to make it easier to avoid hitting it.
