This is a good tank. However it's not like any protank I've had. It's vey wide open for airflow. With the socc .5 heads or the dual rba you'll want to vape it at 40 watts or more. 50 seems to be where it shines. If you use the 1.5 socc heads it becomes more of a mtl tank and tastes great at 25 watts. Its easy to fill and stays shut. You can use the rba head from a subtank mini on it. (you cant use the rba head that comes with this on your subtank mini though) I prefer it with the 1.5 heads they seem more protankish to me. I got it to use primarily with coil heads when I don't have time for rebuilding stuff. It's a great looking tank and holds a fair amount of juice.
