The Diva cup had less suction, so again I assumed it was a size issue, but I wonder if the size of the holes plays a bigger role. My Keeper had super tiny holes and my Diva cup has holes that are easily cleaned with a toothpic. I could be way off base with this theory since so many people have had great success with the Keeper but I wanted to see what y'all think. I'm pretty sure my nethers are average, so I'm thinking I should be able to easily wear a larger cup.
ETA: To the girls with the Keeper, are the holes really tiny on yours? I wonder if mine was actually defective.
