Just a couple things I have found that work for me when using CE3s:
Reinserting the wick is a pain, but lick your fingers and twist the end of
the wick. This will moisten it just enough to stick the frayed fibers together.
When inserting the wick into the
tank, twist the
tank. It's uses the twist of the
wick like a screw, pulling it into the tank.
As mentioned before the leaking is a big issue! Even after using the condom method, i still find leaking an issue.There are 3 holes on the bottom of the tank, one for the wick, one for the vapor exit and another I'm assuming for tank pressure equalization. Buy yourself an eyeglass repair kit, like $2. Force/screw one of the micro screws into that third hole. The tank will still equalize itself from around the wick. 2 weeks now and not a single leak. Put the condom on the battery side, remove the bung, fill to your liking, replace bung, remove condom and vape away! Hope this helps.
