This thing is horrible. I hate it. I wasted money on it and will have to throw it away. It doesn't leak but the vapor production sucks, flavor sucks too - almost none. Wicking is very poor. Instead, it likes to get hot at the bottom so that it almost burns your fingers. I cannot understand why. Tried changing various
coils, putting more cotton, then much less cotton, adjust
juice supply. Nothing helps. All I got as a result is a vile taste like burned wick or something, and I cannot get rid of it even after changing both
coils and cotton. Don't recommend it to anyone.
