I've wicked mine with silica although I use cotton for everything else. I can dry burn occasionally to clean up the coils but I've got the same coils I built the day I got it a few weeks ago. I regularly change flavors once I've emptied the tank without any issues. It's a wonderful dripper that I'm not always fiddling with (or should I say not always dripping into).
