I finally have my first regulated device with temp control and so forth. Using the Evic VTC that I won right here on ECF. I have the firmware upgraded and I am using the Ego Mega. My question is what wattage is good for a vape. I have found if I go above 20 watts it is like a nasty nasty flavor that taste like burning ... hairs (the only descriptor I could come up with LOL) Is there something wrong or is it just my juice is not good for the higher watts?
