Good quality
The flanges are exactly the same as the original flanges that come with the pump

Awesome
Better than the original NCVI ones my pump came with. Slightly more oblong and the silicone is less wide so it’s more comfortable and less likely to have the silicone break from the plastic like my OG pair

Good
They are more of an oval then circle but if you are fine with that they work well.

Just what you want
Great quality, the box was intact and the pieces were actually nicer than the ones that came with the pump.

Work well
These flanges work well. I just recommend making sure you measure to get the correct size.

Nope
I liked the concept of them, I seen the medela ones and thought these would work just as well but for a cheaper price. The part that connects into the connectors was very big. I used the medela pump in style. Since I didn’t use them I simply retuned them and bought the medela personal for flange.

Not Medela compatible
I bought these hoping they would work with my Medela pump and they don’t fit. Still very good quality. Wish they would have included the measurements of the opening or something.
