The new galaxies mtl tank has a bulbous tank option that looks similar.
I've got the mini goblin 2 and 3. Offered really good flavour but it was a bitch to coil and as you say you lost a little bit of finger every time you moved the airflow. Plus if the bottom of the tank touched anything it pissed it's pants.
I left the ijoy as on release there was mixed messages as to if the coils where going to be interchangeable with the nautilus and I knew full well ijoy would soon drop them.
The mini triton gets my vote for lost tanks of yester year. It was a really advanced tank but they released it at the same time as the triton and everyone was pissed off it wasn't a sub ohm tank.
Top fill, juice control and more airflow options. Ahead of it's time. It actually work's so much better with the 0.7 ohm coils and the nautilus 2 drip tip. Tidy too.
The kanger protank 4 too. Came with 1.2 or 1.5 coils and a rba plus you could use any of the sub ohm coils. Literally was the Swiss army knife of tanks and the coils lasted ages but as normal kanger where just behind the times.
