Nenesupply 1st Generation 19mm Flange Insert Compatible with Elvie Stride Flange Pump Parts Medela Momcozy Spectra Flange Willow Reduce 24mm to 19mm Use as Elvie & Medela Insert

I absolutely LOVE these inserts. I have the Elvie original (double pump) and recently received the Elvie Stride pump from my last pregnancy. I measure on the smaller side, so in the past I had to buy a 21mm flange. I never realized I was still using a size bigger than I needed for optimal output. In the past I used BeauGen cushions for my double pump, but they need to be folded or cut to fit and easily wear over a short time. These inserts fit perfectly in both pump flanges without needing any modifications or purchasing of additional flanges. (Note: these only fit in the 24mm flanges that come with the pump). They are sturdy, simple to insert/remove, easy to clean, and make my heart happy with the matching accessory colors! I highly recommend getting an accurate measurement a few minutes after nursing/pumping to determine which size is best. I assumed I’d be a 19mm initially, but after they came in I saw they were still too big. I used a circle stencil to get my exact size (13-14mm) & added 3-4mm to find my inserts (17mm fit well for me). If you measure on the smaller side, I highly recommend these for your breastfeeding journey. You won’t regret it!

These flange inserts are amazing. I did not want to have to purchase entirely new pump parts for smaller flanges. I have 2 different pumps and these fit in both perfectly. I really believe that they have helped my milk production increase, which I desperately needed. I will make sure I have these on hand during the rest of my pumping journey and do not plan to pump at all without them

I have an Elvie Stride and a Medela Freestyle Flex and the flanges that came with them were too large. Because the flanges were too large my nipple would enlarge to the size of the flange and that left me with very sore nipples. The flanges for the Elvie are $29.99 and the smaller size Medela flanges are $18 I believe. I didn’t want to have to buy two different sets so I purchased these and they fit both my flanges just fine. The material is more rigid than I thought it would be. I’ve used them a few times on both pumps and they are more comfortable. Although I’ve read that proper fitting flanges give you a better output, I haven’t noticed an increase in volume of milk pumped. When using the Medela flanges it blocks out my view of the milk coming out, which is slightly inconvenient because I get clogged ducts so when I pump I try and massage the breast to see if I can help the let down and it’s hard when I can’t see if milk is coming out. That’s the only issue I’ve had with them.

I love these inserts , I use them everyday with my eufy s1 pro , they work great for my elastic nips !

I love the color of these inserts but I didn’t realize how difficult it would be to use the not transparent inserts. It’s hard to center your nipple in the flange when you can’t see where it’s at. I also don’t like that the edges of the inside are not as smooth as other inserts. It kind of hurts to use them. I do like how soft they are to the touch though.

Fits with the elvie stride pump. It’s not completely transparent, which I wish it was. But definitely recommend this semi transparent over the green. It was a little tricky to figure out which size I needed, but I ordered multiple sizes to figure that out.

I wish I’d known about sizing earlier in my breast feeding/pumping journey. But I discovered that towards the very END. Pumping was painful until I purchased these inserts and they were great! I used them for my Elvie and my Spectra. It was a million times more comfortable, and I felt like I pumped more- I didn’t pump much anyways, but probably because they didn’t FIT me before these!

One size does not fit most when it comes to pumping. I have an Elvie and Spectra and have been trying to find an insert that works in both flanges and the correct mm needed for a more comfortable pumping experience. I’m so happy I came across this product. The insert is very easy to insert on both my pump flanges, it’s pliable, and soft providing comfort. It doesn’t “stick” to the flange like other brands have and it does not require a lubricant to insert it into the flange.

Annoying they can’t go in the dishwasher

It will probably get the job done with some pumps, but didn't work well with my Elvie pumps. It has to be adjusted and cut on some parts and still didn't pump too well.
