2PCS Flange Insert 17mm Compatible with Medela/Spectra/Willow/TSRETE/Momcozy S9/S12/S9Pro/S12Pro Breastpump 24mm Shields, Reduce 24mm Nipple Tunnel Down to Correct Size, Pump Parts Replace

I love these inserts! I use them with my Eufy S1 Pro and they fit great with it. I have also used them with my Spectra but they are a little harder to fit. I actually like them more than the flanges that came with my pump.

These inserts work great in my 24mm Spectra flanges! They are easy to insert and remove, and they are easy to clean! I will definitely repurchase!

These made my daughters breastfeeding journey so much easier and more comfortable! Great product.

works for my willow go, baby buddha 2.0, ameda joy plus and momcozy m5

I really loved how this works for the medela hand pump, since the standard is 26mm. I needed a flange that was smaller to get optimal suction for milk supply without damaging my nipple. Slides right in, and easy to clean!

These work very well. No pumps come with my flange size so I always need to purchase inserts. These definitely get the job done and allow for good suction.

These are great, they are easy to get in and out of my flanges, wash nicely and create a nice suction for my pump. The silicone is very soft and I like that they are clear so you can see thru them unlike other brands that have a frosted appearance. The price is perfect so you can purchase a few for back up. Definitely recommend and will buy again.
