I am loving mine and have hardly picked up a dripper since getting it. I am sure I have much still to learn but I am going to get a couple more. I have had recurring hot spots but have kept them at bay by dry firing in pulses till the coil is firing correctly (heating from the centre out). I am only using a single wick so every time the tank is low I can hold the kraken at an angle with the juice away from the wick and do the dry firing. It keeps the coil and wick clean, gets rid of hot spots or hot legs and keeps it working great. Good luck with yours.
