I just got mine a few days ago. I had to glue the magnet back on the switch. After about 6 dripping sessions today, it stopped working. Checked all connections and couldn't find anything. I'll have to work on itore tomorrow. If it's possible to make it reliable, it'll definitely be worth the work put in. Just a little nervous at the moment.
One issue I have seen with the one I received earlier this week is with the adjustable top pin. When I screw a tank on it screws down the "non "reversed threaded top pin as the tank bottom positive pin contacts it. It will work for a little while and them it seems this adjustable top pin screws in some more and loses contact with the tank. It is a intermittent problem when it happens, sometimes it fires and sometimes it doesn't fire. It is like it is just barely making contact. I can remove the tank and back the adjustable top pin out and it will work ok for awhile. I put an air flow controller on top of the mod, between the tank and the top pin. The tank does not turn the positive pin in the air flow controller. This solves the problem for now.
The adjustable top pin screws very easy. Need to find a way to make it harder to turn. I thought about putting some Teflon tape on the threads, but I think that could block the flow of electricity.
