I bought a kbox mini 6 days ago and I started having problems today. I am using the 0.5 ohm occ and today it started jumping ohms like crazy. It then went to 9.9 so I tried switching to the 1.5 ohm occ assuming it was a problem with this but it didn't fix the issue. I took it apart and put the 0.5 back in and it started working again but not at 0.5 ohms it usually sits at 1.0. If I hold the dial the changes airflow the ohms go way up again. I am going crazy trying to figure this out. It also seems to go high if I screw the tank in tight to the box. I hope someone can help as this is really helping me quit cigarettes. I went from 1.5 packs a day to 2 cigarettes max.
