money saver
these have helped me save so much money on milk bags since I am home right now, easy to use just remember once you press pause to switch the dial to 2 so the milk doesn't spill out. that is the most important thing to remember! I have forgotten a few times and spilt some milk. after using these for a few months I love them and pumping had been much easier when on the go

Game changer
Amazing! I tried the willow before and it was painful to pump. The Elvie is very comfortable and painless. It makes pumping a breeze. I have made breakfast, did laundry, sat in the yard all while pumping. Itโs easy to clean.

Size yourself!
Willowโs quarter/nickel/dime sizing guide is trash. Find a printable nipple ruler online and make sure to get the right size. The 24 mm work great with Freemie inserts! The 21 mm is too small for the purpose.

You will lose your milk with this pump!
Please don't waste your money on this pump! I promise it will make your milk stop! There are so many things wrong with it that i can't even begin to tell you. For one, if you use a flange smaller than a 21 than you have already wasted your money and you WILL NOT get a refund! Also, there is no let out for air so you are in CONSTANT suction and that makes for very sore nipples! You can't use the app with a android phone but they will not tell you that and will walk you through the steps and waste your time for hours untel you read the reviews and find out it's not compatible. Cushions do NOT work with this pump! I have tried and wasted yet more money. It's a fault product that's marked to women and we give in and buy it bc pumping and breastfeeding is so time consuming. Please just don't! The biggest issue is it's doesn't empty your breasts. It's just not possible for this pump to do so. YOU WILL LOSE YOUR MILK!

Glad to find the right fit
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.

Quality
These work better for me than the containers. I use with the BeauGen cushions and coconut oil.
