I have an Igo T dual coil rda thats giving me some issues. I can build coils without any trouble that work fine, but for some reason when I do a dual coil on it both sides work fine at first. Then after a day or so one side (same side every time) quits working. I can play with the post screws a little and it works fine for a few hours then quits again. For a few days I can play with the screws like that and get it working again, but about 5 days after I build it that one side will not work until I recoil it. Any ideas as to why this is?
