yes , the trick is the pressure, while these arent pressured base like the regular phoenix it still will react that way if done improperly. thats why i mentioned if you fill it and make a error then you might get dry hits or flooding, if done right you wont, but if you do then you must alleviate the issue by blowing through it regardless if its full or not. kind of a reset.
the way it works is once its in motion, the you can vape and vape and vape it all the way dry with no dry spots or issues, but if you fill it wrong then issues will be known right away, either flooding, gurgling, dry hit. If so then follow the method i described and like you did and it should solve your issues every time.
