No i haven't open a ticket, I basically gave up on my Volcano everything has takin a dump in it. The screen, Fire button, Won't read Ohms of my tanks and i have put on 4 different ones. I cleaned the 510 connector and all. I strongly suggest to stay away from Volcano cramming everything into a small mod. I came to the conclusions that Volcano makes shit products, It seems anything and everything that could possibly go wrong has. I have gone through it multiple times being confident in my understanding of circuit boards and etc. This all happened within less than 6months. Now my vape will 1 year old next month from date of purchase
