Bozz I have always liked the cartomizer tanks but I had to give them up because all of them (Boge,Smoke Tec, and the off shoots don't last very long any more and also leak more than when I first started using them. I use the Kanger pro II with 1.8 to 2.4 ohm coils. The coils last quite a while, Vape well at 3.2 volts. (using real Kanger coils) and don't leak out the bottom. I have even taken them apart pulled out all the packing, cleaned the crust off and repacked using organic cotton balls. It works but is time consuming. So I buy 50 coils at a time and replace about every week and a half to two weeks. I use them on two Vamo 2 and a Tesla. I like you vape most all the time. I'm vaping at 26mg of nic per 10ml and am thinking about cutting it back to 20mg per 10 ml on the next batch of juice I make.
You make juice?
