I just received this vape today from someone, so it isn’t new and It doesn’t have the original tank, I’m not sure exactly what tank it is but it’s from smok. I got home and tried to use it and it said No Atomizer, but it was working yesterday for the person I got it from so I’m not sure why it’s not working for me. The tank doesn’t fit completely tight on the mod and just spins, but if it worked for the other person, why doesn’t it work now? Thanks for your help!
