LIFE CHANGING
I am in looooove. I’ve had it for four months now and everyone told me that I’d still need a “primary” pump like the spectra but I was exclusively pumping and hated my spectra. These mommeds made life bearable again. I got just as good output with them (pro tip: I love the legendairy pumping spray), they were recommended by my lactation consultant, not crazy expensive like other pumps, and don’t hurt like my spectra did. If I am wearing a sweatshirt I’ll even leave my car/house briefly with them (though I prefer pumping in privacy). They fit in my nursing bras well, stay put, and I’ve literally never had a single problem with leaking like my friends do with their other brands of wearable pumps. I recommend these pumps to all my friends and my friends who have gotten them love their pumps, too. My friend sent me a text that said, “The Mommed pumps? LIFE-CHANGING.” And it’s true. She took hers on an airplane and said they were fabulous. Because who the heck wants to bring a massive Spectra machine on a plane and become a cow being milked for 20 minutes? No one. I’ll say they definitely aren’t silent, but they’re not loud either. They come with so many extras - little bags for the pumps, extra duckbills, extra back flow protectors, inserts to make the flange the correct size for your nipple, and even a cute little pumping guide. These helped me go from not pumping enough for my little guy to even having a bit of an oversupply and freezer storage! They didn’t have the light up ones when I bought mine, but I feel like I would love the lights to let me know how full they are/help me when I’m pumping at night. But trust me when I say: when you get these, you can put your spectra up on a nice, high shelf and never touch it again. I’m obsessed.

Amazing!
I’m in love! I bought this back in feb right before I went back to work because I didn’t respond well to my other wearable pump and it was to bulky for at work. I love the fact that these are quieter and fit down in my bra better! I use them every single day at least three or four times and I normally can get about three 20 minute pump sessions in before I have to charge the batteries and they are a lot more comfortable for me than my other pumps. These pumps have been amazing and I get just as much output with these as I do my wall pump!

Great Suction
This is a great pump and does a wonderful job expressing my milk. I'm a second time mom and an over-producer. My first time around I gave birth to twins and used the Spectra pump and was able to breastfeed until I chose to stop just after 1 year. This time around I had a singleton and my boobs still produce a ton of milk, but I've returned to work earlier (first time I went back for half days at 3 months until over 1 year, this time I'm back full time at 3 months) and I wanted to find something that didn't necessarily require me to leave my desk 3 times a day. Pros: Great suction - I get just as much (sometimes more!) milk with this pump as I do with my lansinoh pump. 3-5 ounces per breast each time. Relatively quiet! I mean you can definitely hear it, but I can turn on my little desk space heater to drown it out in my otherwise silent shared office. Fits inside my nursing bras. Mostly easy to clean - kind of hard to get in a couple of the little corners but not a huge deal to me, I do use a 21mm flange insert so I have 5 parts from each pump to clean Cons: Charging - while they charge up pretty quickly, there is no way to tell what the current charge is while the pump is on, only when charging. It would be nice to have a display to show remaining battery bc several times it's happened that one will just die in the middle of a pump session - very frustrating. Also the motors look exactly the same so you dont know which one you just charged! I ended up using a sharpie to write 'A' on one and 'B' on the other so I could kind of keep track of which one needed charging. Please make the battery status display a thing!! Memory function - it's nice that the pump remembers the suction level you use on each setting, but I wish it didn't start up on whichever mode it ended on. Sometimes I forget to switch from "expression" to "stimulation" at the end of a session so the next time I power it on it will start up on a strong expression mode which is a shock and uncomfortable. The way around it is to always switch back to stimulate mode before turning off, but would be much more user friendly to just make that the automatic starting point each time you power it on. Somewhat tricky to position - just the design of the pump makes it so you can't see your nipples inside the flange so you can't tell if they're positioned properly (for instance to make sure they won't rub the sides or aren't being sucked too far into the flange), not sure if there's a fix for it, just a tricky thing to get right. Looks a little silly - I am small chested (A cup) and wearing this makes me look a little ridiculous, as if I have DDs lol while it doesn't look COMPLETELY unnatural, anyone that knows me knows my boobs are that big lmao All in all, this is a great pump and has become my main pump. I actually get upset if I forget it and have to use my hospital grade pump. It does just as good a job as my lansinoh and is so worth the money, just could use a few tweaks for user friendliness! Photos show my 13 minute morning pump session. BF baby at 6:45 and then pump at work at 10:15.

Fantastic pumps and at a steal for the price
I am so sad that I didn’t try Mommed pumps before now. These pumps are so good. I wanted the green ones but they don’t have them on Amazon 😢😭 the suction strength is very good it’s strong but gentle. These pumps are perfectly sized and VERY affective they are now my main pumps. I use them all day every day every 2 hours. They are super quiet. They are small but still have a 6oz capacity yet will hold more than 6 ozs. I love that the buttons are right to the point and they are easy to use. the power button doubles as the mode button as well. I don’t use the auto feature but stimulation and expression work very well. I’m so glad these pumps work so well for me I recently bought one of the competitor pumps and paid 2 times the price I paid for these and it didn’t even work for me. I was so upset!! These pumps are fantastic! Great product so happy I chose these over the others I was looking at. Great job Mommed these are perfect!!! They have 12 levels of stimulation and 12 levels of of expression.The auto feature also has 12 levels but it’s not a 2 phase like I thought. level 1-6 are stimulation and 7-12 are expression every 20 seconds the pump will level up by its self it does that from level 1 to level 9 by its self u have to manually switch after level 9 to 10-12. I love these pumps they are extremely light weight very effective and easy to use. 1000/10 recommend

The worst pump i ever used It has very very low suction and doesnt worth the price , dont buy it

Bought this after doing a thorough research and thought this is the best one amount all but it failed all the expectations. The display went in the first 2 weeks and one of the pumps stopped working completely after 3 weeks, It was out of the return period so I could not return nor exchange it. There was no support from the seller and Amazon. Very bad experience. The other pump is somehow working though the display is almost gone. The machine suction power is good but there’s no longitivty of the product. Can’t be buying this expensive pumps every month as it’s very unreliable and can stop working any time abruptly.

It works but Suction is not great. Maybe you have to fix it in certain way which I am after a month not able to figure out. One pump stopped working and there is no product support for my area (UAE).

Disappointing experience with this breast pump. Weak suction, didn't meet expectations. Buyer beware!"

I purchased this july less than 2 months back and now both pumps suddenly became very weak at suction. It is not cheap to fall apart in less than 2 months. I'm totally disappointed.
