It's a Ecab v2 vape, probably some Chinese knock off, the coils/wick replacing isn't confusing me, it's just I thought vaping was as simple as putting the juice in and pressing the button, didn't know you had to replace bits and or upgrade, different voltage ect ect.
Give it a google anyway tell me what I've got? Was only cheap so if you came back and say it's rubbish I'll buy something decent
