What is the Legendairy Milk Duette?
The Duette is a new double electric breast pump. It has twin motors – one on each side – and is most similar to the Spectra Synergy Liquid Gold and the Unimom Opera.

You can see more of how it works in the below stories:

What are the pros of the Legendairy Milk Duette?
This pump has a lot of great features, including the following:
- Some people respond better to stronger suction on one side, while the other side needs gentler suction. You can set the vacuum and cycle strength separately for each breast using the Duette.
- The breast shields are silicone, which some people find more comfortable than hard plastic flanges.
- It’s a closed system pump, so milk won’t get into the tubing and motor.
- You have the ability to pause the pumping session and restart the pump later, if you get interrupted.
- The pump has a rechargeable battery, so you’re not tied to an outlet.
- It has four different modes – stimulation (also called massage or letdown), expression, rapid phase (alternating 5 cycles of stimulation and 5 cycles of expression) and auto loop (alternating 3 minutes of stimulation and 7 minutes of expression).
- The pump has a memory function, so you can set it up to remember the settings that you normally use.
- It has the ability to set a child lock so that if you have an older baby or a toddler, they can’t play with the pump and adjust the settings while you’re trying to pump.
What are the cons of the Duette?
The Duette also has a few disadvantages:
- I don’t love the connected silicone cushion and duckbill – it’s kind of hard to get it into place and get it out.
- It doesn’t have connectivity with an app, unlike some other options.
- This is purely an aesthetic preference, but I don’t like how the bottles are sort of tinted yellow. They kind of look like you ran normal bottles through the dishwasher with dishes with pasta sauce on them.
What’s in the box?

The box includes:
- The Duette breast pump unit,
- Two sets of breast pump parts – two bottles, bottle holders, connectors, breast shield and duckbill, backflow protector diaphragms, and caps,
- Two sets of tubing,
- Nipples and caps for the bottles, and
- A USB-C charger
How to assemble Duette pump parts

Here are the steps to assemble the Duette pump parts:
- Position the silicone breast shield cushion/duckbill inside the connector.
- Put the backflow protector diaphragm in the connector and screw the cap on.
- Screw the bottle onto the connector.
- Attach the tubing.
How to use the different pump settings?
Here’s how to use the Legendairy Milk Duette.

The Duette has twin motors, so you can control the suction and cycle speed separately on each side. To adjust the suction up or down, you press the + or – buttons on the side you want to change. To adjust cycle speed, press the speed button on the relevant side.
The buttons on the bottom do the following (from left to right):
- Sets the memory function
- Selects the side (left, right, or both)
- Turns the pump on and off
- Pauses and restarts the pump
- Changes the mode between stimulation, expression, rapid and auto loop

Comments & Chitchat
Just as an add on for those that dont know, the amber tint on the bottles is because they are made from PPSU plastic.
PPSU is a medical-grade, long-lasting plastic that’s naturally honey-toned and incredibly hard-wearing. It’s the ‘gold standard’ when it comes to baby bottles. Firstly, it’s free from BPA, BPS, and other harmful chemicals, and it is very lightweight and temperature resistant (up to 180 degrees Celsius). It’s also easy to clean and sterilise.
What size flange does this come with? Where can I buy smaller ones?
21s, 25s, and 29s. You need to get the flanges from Legendairy Milk because they are integrated with the duckbill valve.
You can get smaller flanges that are compatible with the Legendairy Duette pump from pumpables. I need a 15mm flange and Legendairy milk doesn’t sell those yet for the Duette pump, but pumpables uses the same manufacturer for their liquid shields. They have all the smaller sizes that Legendairy milk doesn’t have yet, and they’re compatible.
How does this compare so spectra synergy gold?
I LOVE this pump! I use the auto loop feature at the highest suction and speed for 30 minutes, which causes me to have 3 letdowns. I contribute the doubling of my milk supply to this pump. I went from pumping 3-4oz every 3-4 hours to pumping 6-8oz. I also have the spectra s1, but didn’t like it as much. The silicone flanges are way more comfortable compared to plastic flanges. This is now my primary pump. I did a lot of research before buying, and I’m so glad that I bought it. I highly recommend this pump!
Here is the suction strength according to the company:
In Stimulation mode, vacuum (suction) strength ranges from 45 mmHg (level 1) to 112 mmHg (level 9). In Expression mode, the vacuum strength ranges from 120 mmHg (level 1) to 247 mmHg (level 9).
Thank you!!!
How is the battery life? How often do you need to charge it? Does it take a long time to charge? Hoping to use this as a portable pump as well.
@janay: The battery lasts about 3-4 30 minute sessions of double pumping and does not take long to recharge. I’ll usually put it on the charger between pumps and it’ll have a full battery by my next pump (I pump about every 3 hours). Hope this helps!
How does the effectiveness of this pump compare to the spectra s1?
Hi Jennifer! That’s a good question. When double pumping, the Spectra has a max suction of 280mmHg. I cannot find the exact number now, but the Duette is right around that as well. Hope that helps!
