Maymom Flange 15mm Inserts Compatible with Medela, Spectra 24 mm Shields/Flanges, Momcozy/ Willow Wearable Cup. Compatible with Medela Freestyle, Harmony , to Reduce 24mm Down to 15 mm; 2pc/Each

I purchased these for my elvie hands free pump and they fit perfectly they are super comfortable and come out easily for cleaning

These are a thicker plastic than other flange inserts but they work great and they're very comfortable and easy to clean. They're not clear, they're cloudy.

These work great for my pump flanges that plug in the wall or my manual but they are to long for a mobile pump. Great quality and thick so they hold up well and they are very comfortable these are a life saver. (I’ve been pumping for a year)

These inserts are great and fit nicely inside of the 24 mm flanges. I did however have some 21 mm flanges and am able to use it in those. This fits my Spectra, Ameda, Willow Go, and Medela freestyle cups

Perfect fit in 21mm medela flanges. Comfortable. Makes it that you can easily position the nipple. I don't like that it is frosted to make sure everything is ok. It is a great product but I often find myself preferring the 15 mm flanges because the weight of these makes it so have to be careful my bottles don't topple over. Also, it is just another step to put these in flanges and another item to clean.

I really needed inserts for my pumps. These got with multiple pumps.

Got the wrong size. Listing says 15mm but side of the inserts days 17mm.. Didn't realize at first, but it explains why I wasn't all that impressed..they're the wrong size. That being said..you can't see through them almost at making hard to gauge my flow and how things are going.. however, they're very comfortable and don't create any pinching. A little difficult to remove from flange to clean, but once you get it out they clean up well. Works with both the madela & Spectra flanges I use.

I would recommend these
