i bought a KBox200 for my wife because she's had me great luck with her Kanger subtanks. It won't run a dripper no matter what coil setup I've tried. I ordered it online but took it to my store where I shop and they can't get it to work either. It will run TFV4's with no problem but not a dripper. Anyone got anything to offer to help? I contacted Aspen Valley Vapes where I bought it from and they said they couldn't warranty it if it was working. I told them it's not working correctly. Ahhh!!!
