Anyone Own The Wotan Sub Ohm Tank By Damn Vape?

Thinking of getting the Wotan Sub Ohm Tank, seen some positive reviews for it, wondered if anyone had any hands on experience with it and how they are finding the longevity of the coils overall as it only seems to have 2 different coils at the moment to choose from?

The only concern I have about it and although I like the idea of the airflow restrictors you can insert inside the coils, I know I am going to forget them and chuck them away with the coil when I replace it…
