I love my Willow go, this is my second time using it as this is my second child. It works very well! I couldn't imagine my pumping journey without it.

No issues regarding this part since using my Willow go as my primary pump. I use my momcozy bottle washer to clean these and it gets the milk fat removed and these babies dried like a breeze!

I just bought extras to have just in case!

I ordered these to have a spare set of pump parts and they fit just as good as the ones that came with the pump. When I order parts for my other pumps I feel like they never fit the same but these do!

I got these as an extra set and quickly realized how replacing these frequently drastically improves the pumping experience!
