It definitely took some time fracking around before I was able to get them to preform just right (for me). They didn't work well for me in the beginning, but I was determined to figure it out because I loved the TH and vapor production so much. Many sad times of cursing, rage, and crying skyward were had.
What works for me is this:
*Prep yo’ self! - paper towels to put stuff on, ear buds (cotton swabs), tweezers, needle, syringe (filled with your liquid),
1. Take the black plug/bung out (mouthpiece too, and I use a can of air to blow out the mouthpiece of any spare condensation or liquid). Now, these bungs were such a pain for the first few tries, and I've ending up flinging them a pretty remarkable distance. While holding the smokymizer at an angle (mouthpiece side downward, a few inches over the paper towel so that it can just 'roll' out) I take the non-tweezing end of the tweezers and gently wiggle the bung out by putting the tweezers on one side. *Note: gently. After this is completed, I take my paper towel, and CAREFULLY (so it doesn't roll off into a void somewhere) pat it dry, it will make re-insertion easier.
2. Wipe off any liquid from the threads on the battery end.
2. Blow from the battery end to get all the liquid out from that middle tube, and extra juice leftover so that it doesn't mix in with the new flavor I'm putting in.
3. Putting that rubber cap/condom thing (that I got in a pack of the smokymizers) on over the battery end of the threads. Try to put it on most, if not all of the way.
4. Hold the smokymizer at a slight angle, mouthpiece downward, but put the filling hole towards the ceiling.
5. Insert your syringe needle (not all the way, see Astrecks photos of right and wrong, that had helped me out SO much! He truly is a vaping legend!)
6. Very, very slowly start putting liquid into the smokymizer, keeping that slight downward angle. In my experience, I had to learn how slowly to do this the hard way, by having the liquid repeatedly come back out of the hole I had the needle in. What helped me with that was having some control over the plunger part of the syringe while inserting the liquid to make sure I wasn't putting liquid in faster than I wanted to, but I also have carpal tunnel so full, accurate use of my hands is limited a good part of the time (being stubborn and not taking care of it after diagnosis, Don't judge me!
) Remember to leave some room for an air bubble, to prevent over-filling.
(*Note: if you have to set down the smokymizer for any reason, make sure it stays in one place and doesn't roll off the table, but if you can, try to keep it at a slight downward angle.)
7. After you pull out your syringe, the bung-fun begins. The filling hole still needs to be toward the ceiling. Making sure the bung and your tweezers are dry, carefully pick up the bung with the tweezers, but try to keep the tweezers above that little lip at the top, or at least close to it. Don’t tweeze it too tightly though, or it will go flying somewhere. Keeping the smokymizer at that angle (or horizontally, if you want to at this point) try to “feel around” for the hole while looking through the top of the smokymizer to see where that hole is and insert the bung GENTLY, but try to get it at least a little bit of the way in, and then use the blunt end of the tweezers to push it the rest of the way in. Make sure it’s secure.
8. Take a cotton swab and swab out any liquid that is chillin around the place where the bung is.
9. Apply your mouthpiece.
10. Remove the ‘condom’ you put over the threads that are at the bottom of your smokymizer (unless you’re pre-filling it for later, in that case, keep it on).
--As others have said, there is condensation. To try to minimize this, I let go of my button a second or two before I am done taking a puff to get any extra vapor out so it doesn’t sit there and then just drip down my mouthpiece later. Also, condensation can form around the battery end of the smokymizer as well, so there are two reasons for me doing that. It still happens, but happens minimally. When I get down to the last little bit, I do seem to get some drippage.
Again, this is what has worked for me. I don’t know if blowing from the battery end voids some sort of warranty or not. I my goal here is to share as best I could to hopefully help someone else like others here have helped me. If anything I said is incorrect, I’m sure people who actually know what they are doing will chime in
