Hi, looking for some advice. I was using the kanger subtank mini, I loved it except it kept leaking all over the place. I bought another one but the same thing happened so I'm looking for something else. Using my old nautilus mini with the istick which is ok but I don't get the same vape from it. Looking for something with similar vape to the kanger which doesn't leak. I don't want to build my own coils but want a good vape. Any advice please as so many to choose from and I'd rather go with something recommendes. Thanks!
