I'm new to the vaping world, but have had no problems with my joyetech ego-t. been great to me so far, granted it's only been a week and a half, but I haven't bought any smokes since I've started vaping, so I really can't complain! Ok I've cheated from time to time, but can do quite fine without. Don't understand the leaking issues I've read about, guess I'll know if it happens to me....
