I have been using a Kato Square clone for a long time with a kayfun and have been loving it, but wanted to try something different and the Kanger Subtank looked pretty cool to me so I took the plunge. I also got the Kbox with it since the price point is so low. I think they look great together as well. I have always used a high VG liquid in my kayfun, which sometimes I had to prime a few times to get it to wick ok but otherwise no problems. Does anyone know what the recommended VG/PG% is for the Subtank with the OCC coils? Thanks guys!
