I bought a Vamo V5 a few months back and have been using it daily since then, I've noticed that sometimes it just turns itself off. It's gotten worse over time but the other day it just started acting up horribly. The only way that I could figure out how to fix it is slightly unscrew the bottom cap where the batteries go, because it doesn't even turn on when fully screwed in. Is this an issue with the batteries or the actual connection itself on the e cig to the batteries, I'm pretty new to vaping and the vamo is my first E cig, so all the help I can get is appreciated. Have a great day.
