Ok, I've had my trident with my .4 ohm coil in and out of the box I lost 2 full tanks in a puddle that my poor SX Mini sat in over night. Didn't use the tank for a few days tinkering with ideas and with the same coil, I changed the o-ring on the head, and took an extra o-ring for a drip tip I had laying around and shoved it around the chimney. It's sat overnight for the last 7 hours and with it ready to vape and air intake fully closed I have no puddles, no leaks, bone dry and still totally full. Using high vg juice, but was using the same liquid as before. Seems as though the o-ring that's supposed to seal off the top of the coil and chimney wasn't sufficient. If anyone has a delta 2, check the o-ring in that, it's huge. I'll keep updating as the day goes by, going to open up the air intake now and see how things go by sun up in a few hours. But so far, no gurgle, no spit back, and I'm using a wide bore drip tip, so we shall see.
