Grabbed this tank a few weeks back, sorry I haven't gotten this review up quicker.
This is the second sub-ohm tank I've had so far.
For starters, this tank is one of the newer 'top fill' designs. I'm torn on this. It's nice to not have to unscrew the entire tank and refill from the bottom like most, however the openings on the top of this tank are not very big at all. If you've got juice that is in a unicorn bottle, it's quite easy to fill as the tip fits right in. But when you've got juice in a dropper, you've got to be careful filling this up.
Next, I'm not a huge fan of the adjustable airflow feature on this tank. It moves a little too easy, easily twists closed in my pockets. I also don't find a huge difference if it's adjusted to about 'half open' and 'fully open'.
As for the vaping; tank produces some solid clouds. That being said, it seemed a bit harsher than the Atmos tank I regularly use.
All in all, for ~$25 it's not a bad tank... just not for me.
