I recently had to buy a new set of accesories for my breast pump, but the flanges that came with the new set were 24mm and I had used 27mm. I have been searching the web for new flanges my size and came across super Shields. They claim to be better than the original flanges that come with pumps. They don't cause sore nipples, clots, and have been more productive in getting more milk. I have purchased on their website but did not recieved them yet. Had anyone used this product? And if so what is your thoughts on them? How have they worked for you? Things like that.
