I'm posting this to see if there is a home fix before I send it back to Pro vape. Last week my mini quit functioning completely. The button would flash when inserting a battery, but the menu would not come up nor would the device fire. I cleaned the contact pin and battery button with 91% alcohol. Still wouldn't fire and the menu wouldn't come up. Hmmm..... so I poured a small bit of the alcohol into the device, swirled it around a few times, dumped it and let it dry out. Perfect! Worked great for about 2 days, and then started with the same issues. So, I cleaned it out again and let it dry out. Worked great when I tested it and I took the battery out and put it away. Pulled it out today to use it and the same issue. Won't hit a lick at anything. Any other suggestions? I've only had it for 4 months so it's still under warranty, just didn't know if there was something I was overlooking.
