I have only been vaping for a few months, and I have some mods that I don't really care for and some that I wouldn't want to live without. There are still many that I am curious about that I've yet to try or purchase and some that I want but don't have the money for. Also, some aren't so easy to come by (Nemesis Kalafan that I keep waiting to become "in stock")
If you could only have a single mechanical mod and a single VV/VW mod what could you absolutely not do without?
You know there are APV's that are all three, i.e., mechs, vv/vw APV's and hybrids. The best? The SvoeMesto Semovar will handle all three tasks and a nice Kayfun hybrid, as well. Perhaps the best in the world. Most would agree the Nivel chip is the best in the world right now, and is native to the Semovar. $300, or thereabouts, but three PV's in one? I think it's an excellent deal. Good luck!
