i have no problem inserting the cup, but it always takes ages for it to suction. i noticed this morning that the further i put the cup in before it popped open, it suctioned immediately, but i didnt get the same result this afternoon and it took me half an hour to get it to suction (i use the origami fold). the other option that i have is inserting and just leaving the bathroom with out it being suctioned because eventually it will suction, but i don't have the confidence enough to do that and i'd just prefer not to. is there anything i'm doing wrong? i really dont have the time to play around with it 30 min. until it decides to suction.. help?
