NENESUPPLY19mm Flange Insert Compatible with Elvie Stride Flange Pump Parts Momcozy Medela Flange Spectra Willow Reduce 24mm to 19mm Use as Elvie Inserts Medela Insert Momcozy Insert

Allows me to use the Elvie double pumps! Would recommend!

These flange inserts are very easy to use and work well with my spectra pump flanges.

Did the job! Originally had bought a 17mm, but my lactation consultant sized me to a 15mm and I feel much better and comfortable. Came quick too. Sterilized fine as well.

These are fine and helped make my elbow have a suitable flange size. I wish they were a more see through plastic so I could make sure my nipple was aligned properly. But after a few uses that was less of an issue.

They're silicone but they're fairly stiff - for the price, they're awesome. I'm basing them off of the maymom brand - these are definitely stiffer than those so a little less comfortable, but again, overall good!

Like others have mentioned, I wish these were clear. I was pumping for 5 minutes with nothing coming out thinking there was no way, and it was because I couldn't see where my nipple was in the flange and it had gotten snooshed 😂 I use these for the Madela pump in style and they fit well. Also used it for the lansinoh manual pump and does not fit as well, there is a bit of wiggle room and can be a milky mess in there if not careful.

Pros: Product is made of soft silicone which is very comfy and is easy to use. It also sits well in the flange and does not move while in use. Inserts were shipped on time and arrived undamaged.Cons: even though it fit my Elvie stride it's not snug enough so it leaks and the pump ends up not suctioning properly. I bought 2 sizes 19 mm and 21 mm they both have the same issue. When buying the product I made sure it was returnable before I ordered. BEWARE: it is NOT returnable even though it states "Return policy: Eligible for Refund or Replacement." Also like everybody else mentioned it would be great if the inserts were clear it would help a lot with troubleshooting and I could probably fix the fitting issue if I could see how it's working while in the flange.I was so excited when I found these only to be disappointed. I am now stuck with these inserts that I can not even use.

These fit into my Elvie stride perfectly. I don’t love that they’re not see through so it can be hard to line up your nipple. They do the job and they’re comfy though.
