My unit stopped working after 1.5 months. Thought the battery was low, so I went to change it and the battery contact at the top fell out. It had been soldered in there and it looks like it was a cold solder joint.
I sent an email to madvapes, they are out of stock, but asked me to send it back for store credit. What an outstanding group to deal with.
Wished It could be fixed, but it's way up there and I have no idea how to disassemble it. It was a great unit, I will miss it RIP
Good to hear MV is taking care of you. Luck of the draw I guess, mine's been working without issue for 6 months.
