I have been using (and loving) my passthrough for the past few days, but tonight it started acting goofy. Sometimes, I draw and it doesn't vape. (It's an auto, not manual, so no button pressing.) If I turn it a bit, sometimes it will re-activate and start vaping well again. Sometimes i will suck and only get a tiny bit of vapor. I have tried different carts and they all acted the same. Those carts all worked on my regular battery.
The passthrough isn't dirty, there's no gunk or buildup in or around the post or the air holes. (I have only used it a few times.) I also tried lifting the post (as shown in SnowDragon's video) to no avail. I already had to do that yesterday on my battery because I screwed it in to the charger too tightly. That worked for my batt, so I know I did that technique correctly.
Any other suggestions?
I should mention that as I have been writing this, I have been trying to get it to work properly and now it seems to not be working at all... Well, not really anyways. Total bummer!
