The one I am using now isn't pictured there I don't think, although I do recognise the nautilus tank, which I used to use.
I currently use Endura T18 with the prism tank. I saw a video on it and thought I'd try it mainly because it has a top fill tank and easy to change coil. The coils last a lot longer than the nautilus mini coils were, and the ability to top fill is very convenient for me.
I started off with the classic style you have pictured at the top and in all fairness that was enough to stop me smoking initially. They have small niggles like leaking every now and then and sometimes from the mouthpiece too but they also worked for me. Today you have more choice but I would recommend the T18 to a new vaper, it has some the same qualities that I liked about the classic type: top fill being the main one. As a bonus it also has pass through so you can charge the battery via usb while using it.
Thanks for the post :)
