I recently bought my Smok T-Priv 3 kit, it came with everything and the coils worked fine. My coils burnt out in about two weeks so i went to my local vape store and bought a T10 coil, and when i got in my car and tried to screw it on, it wouldn’t thread. I could get it on for the most part but if i tried to put the tank and top on it would pop off. I looked at the coil and it only had two threads on it instead of 3. I went back in and all of the coils in that pack only had two threads. My question is have any of you experienced this, if so is it common?
