I love these inserts!!!! I have tried multiple other brands and these are so soft and very easy to clean. Plus the cute flower pattern is a nice touch. I would buy these again.

These are very helpful especially since each nipple isn't necessarily the same size. I get a better pumping experience with them and it is very comfortable

I'm a second time mama and I always wanted a Willow. I decided to get the Willow Go and the inserts. They fit perfectly and I've been pumping consistently. They have been holding up and I am loving them.
