  • A must-have addition to the bags
Color: Milk Container - 24mm
These containers are a must have additional accessory. They make pumping for bottles accessible and save you on the cost of the bags. I read a few other reviews talking of leaks and spills and here is what I have to say 1) read the instructions. They will fix the leaking issues that occur when the pumping is done (there IS a learning curve but it’s worth it to read the short instructions) and 2) pumping with these is not spill proof like pumping with the bags is. You can still move around but bending over is a “no.” Temper your expectations: will doesn’t claim that you can stand on your head and pump with these like you can with the bags Overall a 5-star review and I love pulling unit he bags and using these containers. 👏🏽👏🏽👏🏽👏🏽 ... show more

  • Good replacement... willow is mediocre product
Color: Milk Container - 24mm
As everyone says, Willow pumps do not last. Design and Build Quality: The containers are well-designed and built with high-quality materials. The 24mm flange fits comfortably and securely, ensuring efficient milk collection. Each container holds up to 4 oz. of milk, which is perfect for most pumping sessions. Ease of Use: The containers are incredibly user-friendly. They easily attach to the Willow pump, making the transition between pumping and storage seamless. The design is intuitive, and I had no trouble figuring out how to use them right out of the box. Reusability: One of the standout features is their reusability. The containers are easy to clean and sterilize, making them a cost-effective and environmentally friendly option compared to disposable bags. They hold up well to regular use and washing without any signs of wear. Storage and Portability: These containers are compact and fit neatly in my fridge and freezer. The lids seal tightly, preventing leaks and spills. They are also easy to carry around, which is convenient for pumping on the go. Milk Preservation: The containers do an excellent job of preserving the quality of breast milk. The airtight seal ensures that the milk stays fresh for longer periods, which is crucial for maintaining its nutritional value. Overall Verdict: The Willow 360 Reusable Breast Milk Containers are a practical and convenient choice for breastfeeding mothers. Their durable build, ease of use, and efficient storage make them a valuable addition to any pumping routine. I highly recommend them to anyone looking for a reliable and eco-friendly solution for breast milk storage. ... show more

  • Not worth the cost, worst pump
Color: Pump 2 Count (Pack of 1)
I am so disappointed in this breast pump. I bought this after having a spectra pump covered by insurance. I wanted a hands free pump to return to work. Maybe I should have went with the willow go instead, but I liked the concept that this could be used in any position (I had this grand idea I could use it while working, etc). First it's very particular about being attached and it does not link well with the app. The biggest disappointment is that it does not automatically come with a milk container but bags are the default. The bags just fill with air and then it tells you they are full to four ounces when there is maybe an ounce and a bunch of air. I did purchase the containers directly from Willow and these are even worse. After pumping when you do their "flip to finish" all the milk spills out all over you--so you've just wasted your pump and now are soaked in milk. And yes, I've watched all of their instructional videos numerous times. Even when you do things right it still doesn't work the way it should. Probably says something that the positive reviews are all from people that got this product for free. I went all out on willows website for the accessories too to be prepared to go back to work and pump for my baby. Now I don't know what I'm supposed to do as this has added so much stress to feeding when I keep loosing all of my pumped milk ... show more

  • Worked great
Color: Flextubes - 2 Count
One of the flextubes that came with my Willow was defective. These replacements worked better than the original! They are the exact same as the Willow and come in a Willow branded box.

  • Glad to find the right fit
Color: Flanges - 21 Mm
After only using a Medela for my first, I have been struggling with incorporating Willow into my routine with my second. I thought it was size 24 originally, and was having a hard time producing. After re-sizing, I purchased the 21. Much better - production and comfort! If you are struggling with Willow, may be worth trying a different size. These are easy to take apart and clean. While the new part was affordable, I do with Willow provided 2 sizes up front when purchased. ... show more
