@figment_oyi, that's nice of your seller. You'll probably really like the SL Class, just need Samsung 30T or 40T batteries depending upon your vaping style.
MTL = 40T
DTL = 30T
A few tips for you, to read coil resistance press in the joystick and then press the fire button to lock the setting. Otherwise you'll end up altering the resistance manually if you try to navigate through the menus.
If you use TC or Joules, use them the same as you would Watts. So 30 Watts = use 30 Joules for example.
