Piping in here as I'm becoming fascinated with the fluxo's and vornado's. I'm taking them fully apart and investigating and trying this and that. I think whats driving me is that when I started, I ordered quite a few 100VG juices. Now that I'm getting experience, reading posts and learning from many of you here, I'm experimenting.
Fluxo's weren't "hitting" like the vornado's and I was curious as to the why...which led me to the discovery of the VG juices being "thicker", so the wicks need to work harder and potentially can't keep up, leading to inconsistent vapes. Fluffing the wicks is not enough from my experience. I have to "unravel" the wicks from their tight braid, trim them a bit so that they don't get caught in the seal (besides, the last portions of the juice performance goes down dramatically anyway and you have to get the juice to the top coil by tilting). Adding that, along with enlarging the holes in the cup seal made a dramatic improvement. They vape almost as good as the vornado's.
Now on to the Vornado's and the leaking problem. Yes, check the top where the tip of the cone get's inserted into the slot. If it is off in any way, it will leak.
Second, what I found is that the cone sits flush on the base of the atomizer. On the vornado's that do not leak that I have, it sits really sturdily. What I mean by this is that it takes more effort to pull it off of the base. The one that leaks (my test one...figure since it leaks, to use it for my experiments), I notice that it "just" sits on the base. I cannot confirm that this is the cause because there is a hairline crack in the cone. So...check the cone to see if there is a hairline crack in it. If you have a clear vortex, you MIGHT be able to see but it's best to take it apart and inspect the cone. From the way you are describing the leakage, my guess is that there is a crack in the cone. This causes the integrity of the cone to be comprimised (sp?), which let's juice seep into the atomizer. What doesn't get burned off through the vaping process will leak out of the center post. If you just let it sit, the juice will just enter through the crack and then out...I hope this helps.
I feel compelled to thank the guys at GV for their outstanding choices in the products. Sure, some of them need fiddling with and once you get past the (damn, if I break it, that's $$ in the trash) mentality and actually start diving into 'em to get them working their best, it opens up whole new worlds. I'm now finally, FINALLY experiencing the e-juices the way they were meant to be experienced. Prior, the liquids were muted at best or provided dry vaping at worst! I sampled some flavors from vaporbomb and was really, really disappointed as I thought I had done everything that needed modding with the fluxo's and vornado's. Plug for LordDavon for his video's and instruction and going just a little further and removing just a hair more wicking, the vornado's come ALIVE! Pina colada, which I was so bummed prior, I gave it another shot and man o'man!!! It is just as described. I could see myself sitting at the beach on a nice sunny day, enjoying that delicious drink, just by vaping it! Awesome, just awesome. I even gave up on the carmel apple nectar juice from GV but Burns_Erin, bless her, I found her to be such a GREAT mentor with e-liquids. Now with the modded vornado's, I can see why she enjoys caramel apple!!! It is flavorful, hits HARD and is just yummy. Now my investment in the liquids will be realized. Can I get a hug?! lol.
