Not convinced...unless Graham leaves the head connected to the O2 IP hose at all times when changing out the scrubber etc. That connection is released every time I remove the scrubber from the case.
Of course I can't answer for Graham, so he will do it later on.
BTW, I have seen plenty of people simply undone the lid, slip out the scrubber bottom and leave the lid hanging in the case.
