How long have you had your sophia? and from your comment, I see you like it. I ordered 2 yesterday, and a leo dripper.
I've had Sophia for a couple weeks. She's awesome. She doesn't leak, great flavor. You can buy the premade wick/coils or diy; whatever suits your fancy.
Now it is important to note that she CAN leak. I tinkered with her adjusting air and juice control to really max her out and see what she can do. Two things came from that:
1) super impressed with her capabilities flavor and vapor wise. Very clean.
2) after she flooded I was out and about and thought i would be done until I got home...this was not the case. I simply unscrewed Sophia. Dabbed the contact with a kleenex. Closed her up slid the tank back down and vaped with her fully closed until I burned the juice out of her naturally. Unscrewed her again and there was half a drop on the contact dabbed that off and was good. No muss no fuss 1 kleenex.
By Leo has a forum on here FULL of Sophia love stories. You won't be disappointed.
