After messing with it for a while I was still getting too many dry hits. So I broke it down again and re-wicked with some rayon. This time, I put the bottom part of the chimney on with the wicks still long and screwed it down a little bit and then took it back off. I did this so I could use the indents made by the chimney as a mark for where to cut off the wicks. Seems fine now. Still not as good as my lemo, but pretty decent.
You could probably do some drilling on the airflow ring if you had the right equipment, this is a small device so that air ring is also pretty small, so you would have to be pretty precise and there wouldn't be that much room for error.
Concerning the question on whether or not I would have purchased this knowing what I know now, I really don't think I can say yet since I just got it today, I'd like to vape on for at least a week before I make a verdict. I will say that I most definitely prefer my lemo tank to the mini fogger, for sure. Better flavor, better air flow, more efficient filling method, and in the same price range. The reason I got the mini fogger was because I wanted to try out a smaller rta that could potentially be easier to carry around on the go (the verdict is also out on this). I'll make sure to keep an update on my thoughts on this device. Thanks.
