### ⭐⭐⭐⭐⭐ Great product!!
*by M***S on September 14, 2023*

These are amazing and so versatile, I bought them to go in a wearable pump I bought and they also fit in my 24mm spectra and Medela flanges which means I get more use out of them! And way cheaper than buying whole new flanges. One of the best pumping parts I have.
