Awesome
After lots of research and YouTube videos, my options were Ellie and this. But I bought this because while working and pumping, it is really important to me that I have a leak-proof breast pump. But the more important thing is that it is sealed so no contact with the environment. I used this for three months while I was working, with no problems, no issues whatsoever. The first two weeks, the suction level was a bit intense but not hurting at all, then it was like nothing, I was not even feeling it. So, overall, I loved it!!

Pumping with this is a gamechanger!!
I watched a bunch of YouTube videos of how to put it together, do the flip and “latch” it. After watching the videos it was super easy to use but on my own I did struggle. But I love it. It doesn’t hurt. Once you get the hang of it, it is pretty simple to use. And the best part I can lay down and pump which is the entire reason I bought it. I definitely recommend. The only downside is buying the bags. I bought the container as well so I have choices but at night definitely using the bag. The Elvie is still going to be my work pump but this is my new home pump and I’m seriously in love. I’m writing this review laying down pumping right now.

Stopped working in less than 30 days
Willow products are too expensive to work so poorly and then just all together stop working. When using the milk bags, they collect so much air in them that they say they're full halfway through pumping. I've then had to use double the amount of bags just to get through one pumping session. I went ahead and purchased the reusable containers. Which is rediculous that they don't come with the pump and instead have to be purchased seperately. It's also rediculous that the original pump only came with 24 milk bags, that's only 12 sessions and again I had to use double the bags for each session because they fill up with air, so I only got 6 pumping sessions out of the original purchase. They only send one charging cord, so you can only charge one pump at a time or purchase another cord seperately. The reusable milk containers are difficult to use and you cannot get them empty ever, they are such a weird design that milk will stay behind in them. I've turned them every which way to get them completely empty. They will never empty all of the way. You end up losing so much milk with leakage, spilling and not being able to ever empty the container all the way. The flanges can go in incorrectly without sealing properly and you have no way of knowing until milk starts leaking out of them. There are a ton of leakage and spilling issues with both the bags and the reusable container. The pump isn't very officiant, I was never able to fully empty out with pumping sessions using the willow. It hurts, I tried multiple flange sizes & repositioning, etc. Which I had to purchase seperately more flange sizes. And Finally, I received my order on October 14th had used the pump intermittently because it is so difficult to use & in the middle of the night on November 11th the left pump just stopped working. I reset it and followed all trouble shooting from the willow site, and nothing. So much money spent for the product to stop working less than 30 days of use. I will never spend another dollar on Willow products ever again.
