RM2 holes that is 
The holes don't just go any where.each rm2 has it's hole lined up with its own bottom part. so don't get the tops mixed up if doing all the changes for coils and wicks at one time.
Remember the hole is supposed to be facing up when you vape otherwise you will experience lots of gurgles.
don't make the hole too big if you want more air flow. Start small and increase little by little until satisfied. You don't want to be stuck with a big hole so be careful.
The hole is an important part of the RM2 so pay attention to it.
That's all
