This is one of the best option for a single coil tank. The deck is easy to build. You can get crazy with a Clapton and go for high watts or screw in the mtl adapter and put a smaller coil in it and flavor chase. Billow 3 glass also fits it.

This reduces the height of merlin by 8mm and reduces the capacity from 4ml to 3ml. I did not notice a significant difference in flavor. Makes the merlin look better on smaller mods. Billow 2 nano glass fits as replacement glass.

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.

Works fine in Wattage mode and isn't overly huge for a dual 18650 sqounker. I don't do TC anymore so didn't test that. Menu is big and colorful. It's good mod for sqounking at high wattages.

Tank is good. It vapes similar to Merlin without any inserts. Flavor and vapor are good. Inserts work well. I prefer it without them as restrictive lung hits are what I like
