  • Easy to clean and well packaged.
Size: 4pcs-17mm flange insert
These 17mm flanges have been great! One of my favorite things about them is how versatile they are—I can use them with multiple pumps, including my Momcozy and Medela, which is super convenient. They arrived well packaged and are exactly as described. They’re also easy to clean, which is a huge plus when pumping multiple times a day. The fit works well and they feel comfortable to use. Overall, these are a solid option if you’re looking for compatible, easy-to-maintain flanges. I’m very happy with them and would recommend! ... show more

  • Works well but some difficulty fitting into medela flange
Size: 5size-flange insert
True to size, strong silicone but eventually got loose so I had to throw them away. They lasted 4.5 months. I did find that it was slightly difficult fitting it into my 24mm medela flange

  • Fit perfectly
Size: 5size-flange insert
Fit perfectly in my spectra, I was worried they wouldn’t match up to my previous inserts but I actually like them better. Easy to put in and remove

  • Okay
Size: 5size-flange insert
Yeah it’s a good product, I just wish I read the specifications a little better. Because of one of the pictures I thought I was getting 2 of each size since it showed each size x 2 so I was under the impression I would get two of each. Now I need to buy a whole new pack because I need another size 17mm 🤦🏻♀️ smh ... show more

  • Great starter kit
Size: 14pcs-7size flange insert
Great starter kit to functionally get an accurate sizing when starting your pumping journey

  • Flanges
Size: 5size-flange insert
Comes with one of each size and has helped me out so much! They fit all 24mm cups but not any others. They have a ring around that makes the suction stand and not let air pass through!
