My wife and I both currently use each a pair of kayfun lite plus v2 by Ehpro. After using these tanks for close to a year now, we both are constantly plagued by thread lock, to the point where we are sick of it... I'm thinking of purchasing some authentic Kayfun lite plus V2 tanks. My question is, do the authentic tanks suffer from this also? We are still very happy with the vape we get from our current tanks, and the lowered price of the authentic Kayfuns would make it well worth it if we no longer would have to put up with this problem. I'm hoping someone has some advice on this. TIA
