Bought another mini riva nova for my ego twist so I could vape two different juices. Came with the 3 attys and have just spent the best part of an hour getting covered in juices as two of them just keep letting vape into the tank, surely that isn't right? So I checked and found that two of the attys have no coil around the bit that heats up and I don't mean the metal piece that goes on top, would that be the problem? They are now in the bin. They don't last very long either, they tend to die after filling about two tanks. Wondering wether to go back to boge cartos never had a problem with those!
