I have been using the drunker for about 3 months now and have been through about 5 of them. It is the best experience that I have had vaping so I stay with it but there are some issues that may be causing this. First, the positive connection is not a securely fasten type deal. The positive connection comes up through the center post which has to touch the little metal plug under the top.
I've found a couple issues with this design:
first, I think buildup can separate the connection because when it stops working I just unscrew the top a little and screw it back in to hopefully grind out some of the buildup.
Second: the outside plastic wall holding the liquid can be too tall and keep the positive connection from actually touching. I found this to be an issue in one of the drunkers that I purchased and diagnosed it by replacing the plastic wall with another that I had from a previous purchase and it worked fine.
Also, the positive is separated from the negative by a small rubber gasket. This is the reason why I have to replace it every couple months because it eventually gets burn marks all the way around and will eventually stop working correctly.
Given these small issues I have to say that this is probably the best device I have used.
