It is pretty simple, i have a nemsis clone from fast tech as I wanted to make sure i liked it before buying a real one. On top of that nemisis is a Kayfun from SvoeMesto. Tastes amazing to me! My wife on the other hand cant stand it, she likes the test of her bottom feeder, tank with replacable atomizer... Each person has their own taste buds and every appreciates tastes in a different way.
But as everyone else said, there are some safety concerns with mech mods and some knowledge that needs to be had before diving into it.
I went from an eGo, to a mech and a AGA-T, put me off vaping and back to analogs. I could never get the right amount of torched SS mesh and wire wraps to work correctly... always tasted like burnt metal, or shorted since it wasnt torched correctly. I read up, read up, read up, and read up some more. Finally broke the AGA back out wrapped it up and loved it, tried some ceramic wicks, loved parts of it... Now i have a Kayfun with a cotton wick, running at .9 ohms.
Do some reading, make sure you know what your doing, and go for it. Its not overly complex. Just read, and enjoy!
