Elvie vs. Willow Go – I Tried Both So You Don’t Have To (2022 Comparison Review)

Hi mom, I see you are searching for the best wearable pump for your feeding journey. Whether you’re pumping exclusively or looking for something to complement breastfeeding, I’m here to help. I’ve tried six different pumps including the wearables – Elvie and Willow Go. Here’s everything to know about how they stack up against each other and what you should buy.

By the way, I paid full price for both of these pumps, so this is a really unbiased review. Let’s compare each of the important features below to help you decide which is the most important.

comfort fit

I admire both pumps for their comfort and fit. Each can fit under a nursing bra, or even a regular soft bra, without forcing me to change to a pumping bra like a standard pump.

Go willow Larger at 5.3 x 3.1 x 4.7 inches, it weighs 13.6 ounces. Elfie 5 x 4.3 x 2.7 inches and weighs 7.4 ounces. The weight difference is only noticeable if I use the Elvie for a week or more and go back to Willow Go. I find it simple enough to fit on my nipple, though there is a huge difference when it comes to lip size.

Elfie Comes with 24 and 28 mm flanges. For me and many women like me, both are very big. You can buy a 21mm flange, or have an off-brand flange insert to make it smaller. Unfortunately, Elvie doesn’t offer anything smaller than 21mm. While it’s still workable with off-brand inserts, it would work better with inserts or trim that Elvie made for the pump, so that’s a ding for me.

Go willow Comes with 21mm and 24mm flanges as well as a helpful sizing sheet and guide. I still had to buy 19 mm insert separately, but since it’s the Willow brand, it fits securely and I don’t have to sacrifice any suction.

If you go with Elvie and need smaller entries, I recommend willow Because it is softer and more beautiful than the Maymom brand.

winner: Go willow.


Elvie Pump vs. Willow

A persistent rumor with wearable pumps is that they do not empty the breast. I didn’t find this to be true for me. At first, I used a hospital-grade pump and once it was time to put them back in, I switched to wearable pumps exclusively because I hate lead times and get better production with them than with my Spectra, believe it or not. However, some people see a decrease in production.

This may be due to the lower suction offered by wearable vs. plug-in pumps, though the Willow Go boasts hospital-grade suction at 280 mmHg, and the Elvie’s is 220 mmHg. For me this is irrelevant because I can’t comfortably go that far.

winner: Go willow It has higher suction capacities.


Wearing Willow Go – he won’t invite that discreetness

Can we agree that there’s no way a wearable pump can really be a secret—it should at least be made to some Noise and must have a space for the engine and milkshed?

Both pumps will make you look like you’ve gained seven cup sizes. Your outfit choices will make all the difference here!

Some complain that Elvie has lights that shine through her shirt. While true, if you’re wearing something thin and form-fitting, the jig will work either way. I find a scarf or a loose-fitting sweater that solves the problem of visibility for both.

However, Elvie is much calmer. The Elvie can also be controlled by an app while the Willow Go cannot, which forces me to reach for my shirt to adjust the suction.

winner: Elfie.


There is no contest here. The Elvie app will track your pumps, measure your output in real time, and allow you to control your pump from your phone. This is very useful for those of us who have a mother’s mind – i.e. everyone, yeah? – Who doesn’t remember the last time we pumped or what we got.

I can’t understand what’s the point of the Willow Go app, which has a sea of ​​1-star reviews. It is basically a timer with no other functions. My theory is that Willow would rather not give it all the bells and whistles so there’s still a reason to pay for the more expensive Willow 3.0, which has a more robust implementation.

winner: Elvie by FAR.

battery life

Both pumps last five to six pumping sessions, and they’re both rechargeable using a USB charger. Both take about two hours to reach a full charge, though you can still charge partially and pump with either one just in case.

If you find that the battery life is poor, contact customer service for a replacement. Charging should not be necessary after each pump.

Winner: a tie.


You know what mama pumps – we cry over spilled milk! I wish I could say neither pump has a problem with it, but both do. Unless you’re pumping Willow 3.0 And using single-use bags, which aren’t friendly to the planet and require constant repurchases, you have to be careful about bending over, and you definitely can’t just lie around pumping.

Elvie sometimes leaks while pumping, especially if you fill a container and bend over too much. The scale usually catches it before that happens, but if it doesn’t, I have a wet bra that’s annoying as hell.

The problem with the Willow Go is pouring the milk from the pump into a storage bottle or bag. I was always missing some in the beginning though now I’m stuck with it.

However, there must be a better way to design both to avoid spillage.

Winner: Nobody wins here!

Spare parts and cleaning

Additional entries you have purchased

Both pumps have an equal amount of parts that you will have to clean. Both parts of the pump can be put in the dishwasher and I have no trouble cleaning either. However, the Elvie comes with two additional containers of milk for easy storage and less frequent cleanup.

Due to the design of the Willow Go, you have to empty the milk each time into another container to use it again. I find this annoying and I greatly prefer the Elvie’s milk collection system.

winner: a thousandIe

a guarantee

Elvie comes with a 2 year warranty vs. 1 year warranty. There’s nothing more frustrating than running into a problem a few weeks after your one-year warranty has expired.

Winner: Elvie


Obviously, this is huge. Willow Go is currently $329 While Elfie is $549.99. If you need a 21mm flange, you can also add that to the Elvie cost.

The big question is whether it’s worth the extra $220.99 for Elvie.

my choices

As a pump exclusive who only uses wearable pumps, I was very happy to have both. There were times when I forgot a key part when I was on a trip and was happy to back up, I didn’t want to wash parts while out and about and still had a clean option when I got home, or one ran out of battery.

I realize most people will want to buy one or the other. The answer depends on how important it is to track and control the application, the quieter nature of the Elvie, the extra containers/less frequent cleaning, and the longer warranty to you.

Knowing what I know now, if I were to buy one, I would probably pick one Go willow Because it’s cheaper. The app is annoying, but I’ve learned to live with it.

I hope this comparison helped you figure out which one would work best for you.
