Got a Kanger Unitank that never worked right. Got a Clearomiser 30 with my MPV that leaks like a Harley. I work with finicky machines for a living, so I really would not have to work on them after work. I don't want to rebuild coils and all that jazz, I just want something that works and is easy to maintain. I'm currently using the clearomiser 16s that came with my starter kit. Anyone know of anything that holds more juice but works as well?
