I would be willing to bet you have a juice with sugar in it instead of sweeter witch will kill coils in a day. If it is super sweet it is a good bet.ask when you by your next juice. Are you priming your new coil,adding a few drops on each coil then letting it soak for a minute? Do you brake in your coil? Starting at a lower wattage and working up to the perfired wattage. If we can be of help please ask. I have 2 juice co.to recommend. Higgycigs.com and tmaxx.com.great people to deal with.
