I'll try to make this short, I bought an rta so I could stealth vape on vacation. No constant dripping, use high vg, my own coils etc. The instructions are shit and the only way I can see to fill it is a tiny drain plug in the bottom. To say this thing leaks out the bottom is an understatement and I don't know what I'm doing wrong. It's my first rta, does anyone else know a trick for this? Thanks
