Ok, I bought 4 of these cartos so I could experiment with them and use different juices. I took one of the unused cartos and filled it, using less liquid so that non-came out the bottom, trying to prevent flooding. I did blow out the previous one as well for comparison. I did get a little more airflow, but both the carts were harsh. I had previously been vaping some grape in a normal cart so I used the same grape in the carto so I could have a direct comparison. After one pull I ended up having to swap back to my normal atty and take a couple pulls just to get the taste out of my mouth, nasty!
I keep hearing such great reviews and I still have so much hope for them, I feel I must be doing something wrong.
