My wife has run into a bad batch of coils. They must be manufactured improperly because they instantly give off a burnt tasting vape. we prime the coils with juice and allow the tank to sit, absorbing juice before taking a vape. the coils that came with the device worked really well, and they lasted for a significant amount of time. but now with the replacement coils, shes having a very poor vaping experience. does anyone know if anywhere is selling good coils for the Pockex? ive searched around a little bit, and from what i can see, reviewers are giving poor reviews for the coils for the last few months. they seem to be having the same trouble as my wife. please help.
