Hello I'm selling a Smok Rigel 230w Mod with a Smok TFV9 Sub-Ohm Tank. This mod is a great device that runs off dual 18650 batteries. The only quirk I have with it is that the battery indicator is very small and hard for me to read. But then again as I get older my vision isn't what it used to be. Also there maybe be a issue with the airflow vents they are very tight to open and close but they will move. This mod is Blue and Black in color. Any further please feel free to ask.
