I know opinions are like assholes but I'd like everyone's opinions on this. I've read about all the subtanks and people's opinions of different ones. I'm looking for anew tank for my wife at work. She's an RN and has to put it in her scrub pocket. She's been using a Smok TFV4 mini for the last 6 months. It finally broke so no I can buy her something else. I've tried to replace it for the last 3 months but she always says I've still got coils for it. I've thought about getting a Merlin but need one that has quick change coils in case she has a problem at work. I'm gonna get her a Merlin anyway. She just doesn't know it. I've been looking at the Arctic V8 mini and it looks pretty nice. So there's my problem. Please help!!!!
