They were not working due to me lol. A few of the coils I got from Kanger did not work at all. A friend of mine had the same issue. I decided to rebuild them all (whether they worked or not) and use cotton as the wick hoping to eliminate all of the problems I was having which worked. After seeing me success, my friend asked me to do his (he was not interested in learning how to do it) and I rebuilt his as well. Of course now he plans to come to me to rewick with cotton even though I have tried showing him how simple it is lol. Either way I enjoyed building them but was more happy that I could start to actually enjoy the tanks. I had so many issues with dry hits and flooding I was fed up. I am happy that is a thing of the past now...
