I like it a lot.
It was actually really easy installing the coil, and wicking was even easier. My main problem was that the airflow ring was stuck. Eventually, I had to take it off altogether in order to lubricate the o ring. To do this, I had to remove the center pin, and it was only after I couldn't get two different
coils to read right that I realized I hadn't reassembled the thing properly. Got extra practice installing
coils, at least.
It's a bit fiddly with all the lining up of arrows and dots, both of which I have a hard time seeing, but the vape is very nice. I'm using the 1.8mm insert.
