Amazing pump and extremely affordable!
This breast pump arrived yesterday and I am over the moon! I have another breast pump that is a plug-in and wanted a hands-free wearable breast pump for when I need to do things around the house. I researched several different brands and decided to give this brand a try. And I am so glad that I did! I was very skeptical because of the price, thinking that this would not be a good pump considering how affordable it is. But I am absolutely amazed! Has great section and shows the time in which it shuts off at 30 minutes which is how long I pump for anyways. Comes with everything that you need including a nipple sizer, instructions, different size nipple flanges, storage bags for the pump, and two chargeable cords. The pumps are very easily explained even without the instructions. Everything comes apart super easy for cleaning. I absolutely recommend this brand and if anything were to happen, I would definitely re-buy this brand again! Five stars all around!

Great value, perfect secondary pump
I LOVED this. I had to triple feed my daughter for 4 months so I was nursing and pumping all day long and sometimes, I needed to be able to walk around hands free. These got me about the same amount of milk at my spectra pump. Just have to be super careful that everything is connected and sealed prior to pumping. Lost milk a few times because I didn’t double check the seal and it wasn’t on all the way. Great price too!

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

Stopped working after 3 months and they don't honor lifetime warranty
The pumps worked very well at first. So well that I retired my Spectra when I was using MomMed. After daily consistent use for three months, one of the pumps gave out and was no longer able to perform like it used to. Because the company claimed to offer lifetime warranty, I reached out to them for assistance with replacing it. UNREASONABLE and ABSOLUTELY INAPPROPRIATE experience with MomMed customer service: If I could give them negative 10 stars, I would. I sent an email to MomMed asking for assistance with replacing the pump that stopped working. The customer service rep who assisted me (Joy), tried to blame Amazon stating that "violent transportation" probably damaged the product (even though the pumps and package arrived in perfect condition and worked fine for the first three months). Her first request was for me to provide her a video of the the pump malfunctioning. As requested, I provided a short video of the pumps on my counter that showed one side full of milk and the other with barely anything. The video made it very clear that one pump was no longer operating like it should. She responded and made a second request, asking if I had record of how much breast milk I typically produce when I pump, so that she could compare. As requested, I provided a photo of what I produced using my Spectra pumps and explained that I was able to pump the same amount using MomMed until it stopped working. She then responded and made a third request, asking me to provide a 20 minute video of myself pumping so that she could compare the amount of milk I produce and stated that I am not allowed to edit the video. I explained that I already provided a video of what I produced with MomMed and then a photo of what I produced using Spectra pumps. Which she clearly stated "photos or videos are welcomed". The video and photo I provided showed a very clear comparison between the two brands. She then let me know that since the video and photo I provided were taken after I had finished pumping, it wasn't enough evidence for them to determine if the pumps are not repairable and needed me to provide a 20 minute video of me pumping without edits instead. First of all, that's the dumbest and most outrageous thing I've ever heard. How on earth would anyone know if the pumps are not repairable from a video of me pumping. Second of all, what an invasive and outrageous ask, to ask women to provide 20 minute videos of themselves pumping to god knows where. I let her know that that was an extremely invasive ask and that I'm not comfortable recording or sharing that with anyone. I also let her know that I'd be leaving a negative review about my experience. She only offered to replace the pumps AFTER my comment about leaving a negative review. It was an extremely frustrating process and I ended up going through Amazon for a replacement instead. They basically market that they offer Lifetime warranty just to make themselves look good, but then make the process so difficult that no one is actually able to get a replacement. I also saw that another woman left a review with a very similar experience as well, so it seems like this is just how they run their business unfortunately.

Was great at first..
UPDATE: replacing the duckbills and diaphragms fixed the light suction issue. NOW the motor itself is not working, therefor there is no suction at all. It will turn on and click but no suction. EXTREMELY frustrated to have bought the pumps, brand new parts and now it’s not working at all. And again this isn’t my primary pump!! I only use it when running errands and once in the middle of the night. I’d like to try new motors but I’m not sure how to get ahold of the seller as customer service is not easy to find, or at least that I have found. Check guess this pump when looking at choices. UPDATE : As a first time mom I did not realize how soon I may have to replace parts on pumps. That being said I figured out my duckbills had little tears in them and this was causing the lack of suction. So if you didn’t know like me, here’s your sign to check your duckbills!! I replaced those and the pump is back to normal😅🤪 I am about 8 weeks PP and I didn’t start using this pump until 3 weeks in, so I’ve been using it for around 5 weeks. The pump started out great. I felt the suction was great and comfortable. I could use this pump or my wall pump and thought they would both empty me equally. I loved how discreet this pump is, it’s not too loud, and how it would empty me when I needed to keep moving at home or when I had to go out. Now about 5 weeks into using it the suction has dramatically decreased. It has decreased to a point where I have only use it when I am full and know even the light suction will pull out some milk. I like to pump after nursing to make sure I am empty, but I can’t use these pumps now to empty because of the lack of suction. I would wear it for 20 minutes and next to nothing would come out, but then I’d use my wall pump and get nearly 3 ounces out. And even after pumping when I am full, I will pump for at least 30 minutes and not feel empty. Which again I have tested to see if I actually am empty and will pump with my wall pump and will get ounces out after trying to use this one. I am not sure if something with the pump can be replaced to fix this, but I am very frustrated it went downhill so quickly. All baby and PP items l, especially breastfeeding items are so spendy and add up fast, so I am very disappointed to have spent the money on this for it to not work after such a short amount of time. Especially considering it is not my primary pump. Great pump at first, or as long as it keeps it’s suction unlike mine…

BUY THESE!!
AMAZING! I’ve had these for several days now and can confidently say I love them more than any pump I’ve ever had! I was nervous about these but I would one hundred percent recommend these to anyone!!! I’ve had 2 plug in pumps and one set of wearable willows before and these are FAR better than them all. Pros: light weight, multiple settings, multiple suctions levels, they keep track of pump time, and are very easy to clean! Cons: these are a little louder than I would like but not obnoxiously so. The suction even on the lowest setting for the letdown mode could be less as it can be uncomfortable but not painful- this also could be because of my baby’s latch being poor with his tongue tie and thus I’m already sensitive and sore from that. Overall- I LOVE THESE! I get GREAT output from these without all of the hassle I had with my willows or being stuck next to a plug. If you’re hesitant …don’t be and BUY THESE!!!
