Hi Balázs
Really, not to put you down, or anything like that, don’t get angry, but you have only just sampled the dl…
True, we are not the same, my buddy has been vaping the same flavor (hazelnut) for about 15 years from an atomizer tank, and only buys a new device when one of the TWO sets wears out. In my opinion, he is the real target audience for whom this electronic cigarette line was invented in the first place. It specifically replaces the analog cigarette for him, with the only change being that he quietly switched over to (very) tight dl. 
And I am the other extreme, I don’t think there is any kind of e-cig that I haven’t tried yet (that isn’t on the shelf)
