Does the pump shut off and alert you if it reaches 5oz full?
Best Answer: The eufy S1 Pro Wearable Breast Pump has a milk collection capacity of 5 ounces per session. It does not automatically shut off when this capacity is reached. Therefore, it's important to monitor the milk volume during pumping sessions to prevent overflow.
Is the top closed/ automatic shut off so milk does spill out the top?
Best Answer: Yes, the eufy S1 Pro Wearable Breast Pump features a closed, leak-proof design to prevent milk from spilling out during use. It utilizes a secure double seal and a reinforced lower half to ensure that milk remains contained within the pump.
What is different about the pro?
Best Answer: The S1 Pro has a case that charges it.
Is this a hospital grade pump?
Best Answer: It offers up to 300 mmHg of safe, hospital-grade suction.
How much milk does it store in each pump?
Best Answer: It can hold up to 5 oz of milk.

Amazing wearable
I don’t often leave reviews but I LOVE these pumps! My output with them is great, the heating feature is amazing, and they’re easy to clean. The carrying case is super easy too and the charge lasts forever.

Wanted to love it more
Love some of the features like the heating element, different app settings and being able to log the amount pumped.
Downsides: case does not hold a charge for 5 days, I end up charging every 2 days as an exclusively pumping mama. Wish there was also a way to charge the pumps without the case. Pump is also pretty loud.

HORRIBLE
I’m sure this review will be take down. I wrote into support to have them issue a refund. My breast pump did not work for my boobs I’m talking an hour session and coming off the pump with full boobs. I tried all the tricks online. Unfortunately nothing worked and as to try to avoid mastitis with my one month old. I figured I better return and get a new pump elsewhere. They told me they would make an exception and accept the return but then as soon as I sent my pump in they rescinded that…

Great purchase!
I purchased this pump in January 2025 with the intent on using it when returning to work. 7 months later, and it is still great!
I love this pump. It is easy to use and travel with. I use it multiple times daily during work, while driving, and have taken it on trips to use overnight. The heating element is a nice touch! There was even a recent firmware update for new pumping patterns (including a power-pump mode).
The charging case makes it easy to keep the motors charged, and for…

Poor suction and seal..
Honestly, not impressed. Suction and seal aren’t great. Milk leaks out which is a bummer. The idea of a wire free pump is great but not the best for milk supply. Wouldn’t recommend.

DEFECTIVE PRODUCT
First of all, this pump with the charging case is not a cheap purchase. Eufy claims there is a warranty but after a week of correspondence about my defective pump, Eufy has acknowledged that one of my pumps has a motor failure and instead of replacing it, they offered a measly 10% partial refund so now I’m stuck with a pump that does not work or do what it’s advertised to do… super disappointed by the terrible customer service.
Also, I bought it a little over a week ago and it was advertised to have a free gift (a baby monitor) well that didn’t happen either.

Love it
Honestly this is the best wearable i have had yet so far! The heating element really is comforting. The suctions not too strong although i keep it on q low setting. I have used some that were so strong on level 1 i couldnt take it. The app is pretty great too! I will add ive not had it long but so far it has not let me down

Love the design and the heated feature
Love this pump. The heated feature is what sold me! Easy to clean! Charge is long lasting and the case isn’t big at all.

Absolutely yes if you can afford it
Pricy but with every dime. It works really well for a wearable pump to extract milk. Love the hearing feature especially when I have a clog. Would repurchase if I have another child.

Hesitant, but love with them
Love this pump! Short version: it gives me about the same output (sometimes more!) as my spectra gold. I was hesitant with an unknown brand and the cost, but would buy it again if I had to do it over.Profs:- hardly any learning curve! Some wearables are hard to navigate or complicated- Love the heating feature.- flanges are more comfortable compared to any other pumps I’ve used (comfortable is a relative term in the realm of pumping I guess! lol) but the shape and material is really nice- App is…
