So, I'm new to all of those but I love it so much. Recently purchased a kangertech sub box mini, black and white, which came in a kit which had the box, tank, charger, two coils, and another different coil as well. Well I've had it for a week and I have been having this 9.9 ohm issue. I've changes my coils recently because of a burn issue but that has been taken care of. This brand new coil will not let me use the vape its just constant dry hits over and over and its reads 9.9 over and over as well. I need help fixing this because I can't return the box and I haven't been able to use it for two days because of this issue
