For all you mech mod users, why do you go with a mech over something like a DNA30/similar. I'd like to try something a bit less restrictive than my sigelei Zmax, and have been looking into both. I'm more than familiar with the electronics theory, so I'm looking for your subjective experience. One of my questions, other than all around experience, is how many vapes you get before you notice a change with dropping voltage. 10? 50? 100? I know coil builds will have a huge effect on that, but I'd like to hear your experience. Any input is appreciated!
