The willow go pump has
[This review was collected as part of a promotion.] The willow go pump has been life changing to help with pumping on the go! I had to look up trouble shooting a couple times and the website helped me fix it within a few minutes! Just know the replacement sets doesnt include the flange/front piece of the machine. So nice to have two sets of parts so i only need to wash my parts once per day!

These are high quality parts
[This review was collected as part of a promotion.] These are high quality parts that work well and are easy enough to clean! I just pop them in my bottle washer or dishwasher, and they don’t really touch milk so it doesn’t need to be done everytime.
