Hi Zoli,
What PG/VG ratio liquids do you use with the tanks?
My first build wasn’t very successful: after the usual coil winding + wicking, I wound it, assembled the tank, closed the liquid intake, and filled it about halfway.
Afterward, I opened the liquid intake so that one opening was free on each side, then started using it. The tank started gurgling properly right from the beginning, and within a short time, it pushed almost all the liquid into my mouth.
I used a 2.5mm core, 0.8ohm MTL Fused Clapton, BP Mods cotton, I made sure it wasn’t thinned out too much and covered all the intake holes. I vaped it at 15-18W.
One thing that’s already noticeable is that even with all the airflow holes open, the MTL airflow is very tight, a real satisfying feeling
