I've been vaping on mine for 3 weeks using all sorts of juices. No issues with my clear insulator. I check it every time I clean my coil.
Done Kanthal builds down to 0.4, and nickel builds down to 0.16 (for temperature control). I've vaped juices using cinnamon, fruity flavors, citrus flavors, max vg, 50/50 blend, 70/30 blend, and anything in between..
I've accidentally hit this at 110W on my Sigelei 150w mod on my 0.4 ohm coil, and other than having to change the cotton, had no ill effects to the insulator.
I understand that you've had problems with your RBA's insulator, but every single post you've made on the subject has been on how evil and awful they are that they didn't fix the problem for you immediately, and . I don't understand how that these posts about your single incident of a broken insulator can be useful, nor appropriate for the rest of the folks who are out there attempting to find the best way to use their devices.
I'm not trying to be mean, so don't take me the wrong way, but there's now 3 or 4 threads on this subject on the board, most of which were started by you, along with over 20 pages of you discussing it, and also not letting go and derailing others' discussions that are going on discussing builds, or flavor, or even reviews.
Again, I'm not trying to be a jerk, but there's a saying on 4chan, which is "/b/ is not your personal army".
I understand you have spent a lot of time on reddit, which imo, is one of the more "aggressive" product forums out there overall. There seems to be a high level of self-centeredness over there, requiring anyone who could have potentially "wronged" them to get everyone to pick up arms against their perceived aggressor, and force that perceived aggressor to fix everything immediately, for free, and without thought of cost and time that might go into that perceived fix.
I really don't think this forum is full of the sort of people who are going to pick up pitchforks and torches, storm the gates of Kangertech, and hold everyone hostage until they send out free replacements to everyone, overnight from China, immediately, because we said so.
It sucks that you got a crappy insulator that broke. I hope you get a new one. This is one of the best tanks I've ever used, and I absolutely love it. The flavor is great and it's quickly become my favorite tank, especially compared to everything else on the market.
Don't let one bad experience make you go on a rampage to ruin everyone else's good time. Nobody got hurt, died, injured, burned, insulted, scorned, chastised, nor maimed by the incident.
Please, let us know what happens when you get your replacement, so you can go back to vaping on this awesome, brand new, game-changing device. Please let the ranting about the insulator end. We've totally got your back here.
Thanks.
