iServe Spectra Baby USA - Breast Flange, Wide Neck Breastshield - (Small/20mm, 1 Flange Included) - Replacement Part for 9 Plus, S2, S1, M1 Breast Pumps, BPA/DEHP Free

Exactly what I needed. Works great!

Would recommend, fits as expected

Getting the right flange size made a huge difference in my milk supply—this truly changed the game for me. Once I switched to a size that fit my breasts properly, pumping became more efficient and comfortable. The quality is exactly what you’d expect—nothing fancy, but no complaints at all. It does the job well!

My daughter had a baby and the flanges that came with her pump did not fit. This product was as described and works great! The quality was excellent. Definitely worth the price!

Like many, I was using one of the sets given to you with your pump. I HATED pumping and was in so much pain. I had read about getting fitted for the right size on Reddit so I brought it up with the lactation consultant. Sure enough, I was using a size that was too big. Ordered the correct size and the difference in pain was huge.
