The subtank nano was one of my first purchases with my first apv (cloupor mini 30watt) and it has far surpassed my expectations. Lots of liquid capacity, the .5ohm occ coils are amazing, great vapor production and flavor. The stock drip tip that came with it is a wide bore metal tip, and I have not felt the need to change it as it is very comfortable. It produces excellent vapor quality and the flavor of any liquid I have put in it has popped. The airflow adjustment gives you a wide range of options, and in my opinion is better than the airflow adjustment on my nautilus. The occ coils are very easy to rebuild, the only downside to this is it does not come with a rebuildable deck section like the subtank plus or original sub tank had. Very good quality tank and pairs well with a smaller apv like the cloupor mini or something around that size
