I still use my Lemo2 on a daily basis, not all day, but it's always there... my GF loves her too, we have a total of 3. I love the draw and airflow in the Lemo2, one of my favorite actually. I usually have the airflow about halfway open, 30-35 watts. The KM3 is very different and a lot tighter, it is nowhere near the airflow of the Lemo2, even wide open, still a lot tighter than the Lemo2 half open. The KM3 has the
perfect amount of airflow for me, I love the draw and love the amount of vapor that comes out, don't need more, don't need less
Flavor has always been excellent in the Lemo2, for me, it's not necessarily better or worse than the K4 and KM3, it's different, and it really depends on the juice I'm using. I used to vape my ADV (RY4) in the Lemo2
only, until I bought my first K4. Now it's in the KM3 and it's staying there. That being said, there are some juices that I did not care for in both Kayfuns and prefer to vape them in the Lemo2. All HHV NETs have been outstanding in the Kayfuns, more so in the K4, but that's just me.
