LIFE CHANGING!

It has been life changing since I purchased the Willow. I was initially hesitant because of the price (and commitment to pumping), but oh my goodness it is everything I need that I didn't know I needed. It is QUICK, EFFICIENT, and CONVENIENT - all things I need as a mother of two. Not only that, but their customer service representatives are so helpful, responsive, and quick to help resolve your issue and talk you through anything. You will not regret purchasing the Willow! *This review was collected as part of a promotion.

Changing the game of pumping

This has been a game changer to say the least! I bought this pump as I spend most of my time in the car for work and knew after being connected to many wires and tubes in the car with my first baby that being cordless and hands free while driving would change pumping completely for me. I'm not back at work yet after my second child and have already started using it—what i didn't expect was how game changing it would be just using it as home as well as I'm chasing after a toddler and caring for a newborn. Highly recommend this pump to all moms! *This review was collected as part of a promotion.

The best pump

Willow pump is the best pump I ever have. I'm a healthcare worker and It's very convenient I don't need to take a break just to pump. I just go to the bathroom and put my pump on then go back to work. I always pump while working. The best pump ever! I highly recommend this to my family and friends. 🙂 *This review was collected as part of a promotion.

Ultimate Time Saver With Flexibility

As a registered nurse it's important that I have as much time as possible to take care of patients and this pump allows me to set up within minutes and still be able to stay on the floor and chart without missing a beat. And if your little one is already on the move, the flexibility of being about to go about your day and spend more time with your kids is priceless. You won't regret it. I'm soo glad I made the decision and took a chance! *This review was collected as part of a promotion.
