For those of you who like Protanks, but don't run them on your mechs because of airflow issues and "burned grommets", I can confirm that the Aerotank base combined with clipping off the top lip of the grommet on your head assembly will alleviate any issues and make the Protank a decent device to use on a mech. I have a 1ohm coil in mine as we speak, and airflow is more than sufficient to provide a very good vape. Carry on.
