Okay I've had my carto's since yesterday for the 510. I like them and hate them at the same time 
What I like: Convenience, don't have to fill them up all of the time or top them off. Less parts to fool with (1 carto vs 1 atty+1 cart), easy to draw off of.
What I don't like: low vapor, less throat hit, less flavor, less satisfaction.
So, they have the rubber stopper, easy to remove to fill. When I do remove it and take out the O ring, there is a LOT of filler inside. The little hole in the middle literally closes up once I've dripped enough juice in because it expands. The inside definitely doesn't look like my mom's carto's from SmokeStick which are the only ones I have experience with.
Is there anything that can be done about the lack of vapor/hit/flavor from these carto's? I just plugged in an attycart with my camel/cinnamon flavor, same as what's in the carto, and it's a million times better as far as vaping goes and a million times worse as far as keeping it full goes.
And, because I'm pretty sure someone's gonna suggest I get a tank, I'm looking into that. I'm just wondering what I can do with these while I have them to hopefully make them better.
Also, I've done the trick I read on the tips and tricks forum with the rubber sleeve blocking most of the air holes in the battery to make it draw better, but it didn't really help with my issues.
