Hey guys whats going on. Been using my provari 2.5 for 2 weeks now and loving it. Today I had changed the coils and As Im taking a hit or in the process of taking a hit, it is turning off. After like 4 to 5 seconds of pulling its turning off on me. Is this normal? Or what is happening?? Im really confused because this never happened before. Did I do something wrong and how can it be fixed. Thanks guys
