I always have problems with these. They say they need to be replaced every two months but I feel like I have to replace them monthly. Although customer support is very helpful with replacement under warranty.

Changed out the diaphragm - pumps like new again.

I go back to work and I’m gone for 13 hours a day so this is a must!

Definitely recommend changing these out every two to three months if you use your pump slot. I am five months into pumping with my willow Go and it works just as good as my walk grade.

I appreciate how easy Willow makes it to invest in a spare set of parts! The diaphragms are super easy to use (thank you for the user-friendly design) and easy to clean.
