Quite a setup, my friend! I spent the first two years vaping trying literally everything on the market. When I found the Kayfun, and later the Taifun, then the Taifun GT2, I stopped buying vaporizers, other than the 30 or so Taifuns I now use. Thank you for sharing your experiences on your hardware, and for any difficulties that you, or others may be having. I am definitely NOT up to speed on the latest hardware out there, but, for my purposes, my vape is outstanding, and stopping the hardware hunt, has allowed me to focus on other things including juice making, and my other hobbies, like woodworking. However, the pressure seal issue is with us on all of our various toppers, and I hope that anyone new to vaping will benefit from State O'Flux's outstanding work on pressure seal issues, as this, together with new O-rings will literally solve 95% of issues related to our tankomizer systems. I have added a few new batteries along the way, primarily Provari's, Semo's and Eye's, and I feel fortunate to be content with what I have. It wasn't that way for a long time. In fact, I quite vaping in 2009 and again in 2011 as I could not get enough vape to overcome a 35 year smoking habit. I've been smoke free for about 3 years now, and can see the day, sometime in the future, when I don't vape anymore. But that day is not today, and I have no actual plans to quit vaping. Think I'll try some nice key lime pie vape now! Good luck!
