I was in need of a different size flange for my pump, but I wasn’t exactly sure which size would be best. I loved that this pack came with multiple sizes so I could find the best fit . Upon trying them, it was very apparent the material is great. It is flexible for comfort, yet provides a good seal on the pump. It washes easily. Very happy with purchase!

I purchased this based off of a flange size ruler I got and I still got a couple sizes too big ordered 17 but really need 13 I think so I'm disappointed these sizes didn't match the ruler I was using (not sure whose issue it is). The flange inserts and easy to put in and use and nice silicone feeling. The silicone is also easy to clean as well.

My wife was very upset that her breast pumps with no sizes that fit her. These inserts really helped out the efficiency and pain management of pumping!

Bought these for my spectra s2 and they fit perfectly. These do not let milk leak around them and they are easy to place into the flange.

It fit perfect to both of my breast pump sadly I order the wrong size but the material and everything was perfect I'm ordering a smaller size

I ordered these without measuring but I returned these and ordered a smaller size. They do feel comfortable must say!

Bought the wrong size and customer service did everything to make it right! They went out of their way to make sure I had the inserts that worked best for me. Definitely recommend!

Ended up returning! I didn’t realize it was only one of each size which was my own fault but it returned instead of ordering a new set because it didn’t fit super well inside my flanges
