For milk storage.

Works great

Definitely takes some time to get used to. If you get the reusable containers it limits you to 4.5 oz. Also, for me it's leaked a few times, which I didn't think would happen since it's made for movement. I use my hospital grade as my main and this when I am on the go and need a quick session. It also doesn't connect well with the app, it takes too long to load and the information isn't correct sometimes

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.
