The darker juices are more known for gunking coils, not cracking tanks. Deposits from the juice bake onto the coils when they heat up. The deposits can render the coil useless for vaporizing the liquid. There are ways to deal with it, but boiling might not work. You can rebuild the coil (a different conversation entirely), or you can dry burn the coil (works for some, but not everyone). Of course, you can also just put a fresh coil head in the Evod and vape on.
Oh, I see! I did try to dry burn it as well, and it still tasted burned, but I didn't know that the coil was the problem. Thank you for the clarification.
I've used Sticky Bun in the EVODs - not a problem. The ONLY real problem I've ever had with a juice is Salted Caramel - coil killer for sure! I have never had an EVOD cloud or crack from any kind of juice.
Very good to know, because I am seriously in love with these clearomizers and want to keep using them when I order my Vamo. I will vape without fear.
Thanks!
