Along with a couple of other solutions simultaneously, my LC had me try these in my collections cups with my pump, because it turns out I went the wrong direction and was using flanges too big. I don’t know of anyone who sells 19 mm flanges, and Medela doesn’t for sure, so this was a cool little inexpensive solution to that. I didn’t even know flange inserts were a thing. So now I’m using this brand since my LC does.

These work just fine, but doctor said that the suction of the pump forces the flange open making them bigger than the listed size. I ended up returning them and purchasing the right size flange.
