Review: I use these over the Spectra standard flanges! - These flanges are comfortable and fit into my pumping bra very well. I love that you can snap them out easily and the angle they are made are perfect for elastic nipples. These are much better than the standard Spectra flanges!
Review: Love it! - Love that these are compatible with my spectra. I highly recommend if you hate the big plastic flanges that the spectra comes with! EDIT: still giving 5 stars but these flanges don’t last long. They’re super great for a while but even if you hand wash them, they still start to break down and fall apart. Keep an eye on them so your milk doesn’t leak like mine did during a late-night pump sesh!
