So last month I forgot my sigelei 100w plus in my truck with a half tank of juice on it. Weather got warm, juice leaked out of tank inside of sigelei. I opened the battery compartment and there was juice everywhere, I was absolutely sure the board would be covered. I was sketched out from using it so I ended up picking up another vape. A night like tonight with nothing to do I decided to finally open her up and see the damage. Absolutely nothing behind the plastic... Perfectly fine sigelei 100w that I'm no longer sketched out to use. On the bright side I got my self a new vape. Just thought I would share my luck.
