An almost new dual coil with a hole burnt thru and very dark burnt tasting triple coil. Took apart the triple and all the diapers were burnt and into the matting. Dry burned the triple and put the washed diapers back on and reassembled. Works great again but the burning has me grossed out, it can't be good. Going back to dripping and clearos. Somebody please come up with a diaper that won't burn, because they do produce a lot of vapor. Please don't come back telling me to keep them wet, I have been vaping for almost three years and they burn wet. I dripped into a three coil after every five puffs and after two days took it apart and the diapers were burnt. I never used the single coil cartomizar but imagine it goes the same. Will try new diaper material and if I find something will post in mods.
