Got my AGR+ (Pyrex version) and a set of slotted boge carto's from kidneypuncher.com on Friday. Filled the tank observing all tips as seen in pbusardo's video and yet I ended up with a flooded carto and a leaking tank shortly thereafter.
Took the whole thing apart and used an ultrafine needle to suck some juice from the carto, put it back together. I used that ultrafine needle to fill the tank to about half. I noticed that the top of the carto became much more saturated, which shows that even with a really thin needle the pressure builds up and pushes juice into the carto. That also means that if you start the process with a fully saturated carto, flooding it is almost guaranteed. I let the whole thing sit and vent for a couple of minutes before installing the drip tip and then closing the fill hole.
No flooding and no leaking. Good thing. It vapes OK, Flavor is there, but it does not really make me jump up and down either. What I don't like is the heat build-up at the drip tip. Maybe I am just very sensitive, but I prefer a cooler vape.
I have to refill in an hour or so. Let's see how that goes, but this tank might end up in the classifieds, because I really have an issue with the hot drip tip.
Cheers.
