Knowing volts and ohms is important. Turn down the volts. Ohms might be on th low side of what they are saying they are and so too much voltage is going to burn. A coil can get hunky in a few days depending on your juice. Darker sweet juices gunk them up fast. Just the least bit of too dry coil in that state gives you the burn. Some carto mixers are packed too tightly so not enough juice to coils. Dirty coils, not enough juice to coils, too high a voltage means burn. True, Vaperouth is a real thing re taste but its not going to cause burn. Drip your carto. Turn down the volts. Get new carto, maybe its packed better. Think of the $ saved on packs of stinkies and fiddle some more. You'll get it
