I need some help? I have been using my joytech since new years eve now. the first week and a half no problems, then it started to leak, weather full or low it leaks, and you get juice in your mouth. was told to change coil. tried the ti coil seemed ok for one day same problem. now have got some more coils but the are 0.5 ohm ok for half a day then problem back again, and since I have put the new bigger coil in the display has changed. watts at the top, volts in the middle and atomizer at the bottom. dose anybody no what the problem is and why has the display changed?
