I avoid overfilling the tank now, stopping when the oil reaches the top of the wick hole. Today marks the third day, and the oil level has dropped to half the height of the wick hole. I'm curious to see when it will start to taste burnt. This coil has been in use for almost 20 days, which is quite impressive.
This morning, I heard that Lao Wu woke up coughing during the night, but he still refuses to vape, insisting on smoking traditional cigarettes. This demonstrates how difficult it is to quit smoking; even switching to alternatives like vaping is a challenge. Perhaps someone "informed" him about the potential harms of e-cigarettes, causing him to give up using them as an alternative.
The design of this oil tank is impressive. Even with just a little oil left, turning the tank upside down still causes the oil to pool at the wick hole.
Once, I couldn't taste anything while vaping Turkish flavors, possibly due to what they call "vaper's tongue." To prevent this from happening again, I'm planning to alternate between Turkish flavors and Absolute Zero. Since I'm not particularly fond of Absolute Zero's mint flavor, I'm reluctant to fill the tank with it.
When the oil level is low, you can feel the cotton wick saturated with oil being heated by the coil, turning the oil into vapor. After cooling down, the wick reabsorbs oil from the tank, and the process continues seamlessly.
