hello! I am having an issue with my brand new VooPoo Panda Pod System- I used both cartridges correctly and used ejuice in the correct cartridge and nic salt in the other. Both coils in the cartridges burnt out within hours of using them! I primed them and let them sit for an hour with new juice/ nic salt in them before I used each cartridge for the first time. Is there anything I can do or that I am doing wrong? I know for sure that I put the juice and nic salt in the correct cartridges and primed and waited to let the juice soak for an hour, so I don’t get how this happened? Any ideas or anyone know a way I could fix the pods? Thanks!
