### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great material
  

*by H***R on Reviewed in the United States on September 4, 2023*

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!

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Good
  

*by A***R on Reviewed in the United States on August 19, 2023*

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.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Much more practical
  

*by M***K on Reviewed in the United States on September 3, 2023*

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!
