Well then to answer your first questions, you can get a perfectly fine vape from a mech mod, I own a few. One has to be more careful using ohms law when building coils, and you don't have any built in protections. Many people then look toward regulated devices, there was VV & VW, I thought I was done, then came temperture protection, so I tried that. At some point you either realize you like technology or don't. And for some vaping becomes a hobby. I like to try and keep up with it as I enjoy it, as well as helping others when I can. The benefits of TC vaping are more then I have time to write about, but it does take some dedication to learning the technology and trouble shooting. It's certainly not for everyone. I've helped out quite a few friends, and for those that unlike me, don't want to know more then just a way to get their NIC fix, I've set them up with simple plug and play devices.
