Very satisfied with my order, in good condition, perfectly working well, fast delivery, I highly recommend this.
I love my S21 best pump ever! I have motif, Lasinoh, Medela and my S21 is on top of them. It very effective wearable pump 1000% worth your money and time. I have been able to increase my milk supply and started a stash. Thanks to my MomMed S21 !
I absolutely love this pump! It’s very Affordable. It’s a little loud but I don’t mind that at all! It empty me out I always drive and pump or cook and clean and I have no issues I recommend this pump!!
I was in love from the opening of the box. Beautifully presented. All the information you want? Amazing. I was tempted to start a review all on its own, but wanted to try it first. Quality? Hands down fantastic. I cannot praise this thing more. It feels amazing in your hands, the chargers are crazy long (you get a charger for both pumps btw, no sharing) and the feel while wearing it is awesome! I couldn’t recommend it to enough people
I got the MomMed S21 wearables and have used them for 3 days and have loved them! I own a horse farm and can wear these doing chores, dishes, driving...
My stats are (lol):
5 weeks postpartum.
38DDD/E
Not an overproducer.
Exclusively pump.
3-4 hours between pumps.
30 minute sessions.
My other pumps are a Motif Luna standard pump & Medela and Lansinoh hand pumps. Each pump with those options I'd get roughly 5 to 6 ounces total using 19mm flanges.
I have gotten more each pump session with these wearables. This photo is after my noon session, where I'd average 5oz total. I got 10oz! I've actually had to use creams and less suction with these because it's too intense for me. I typically do 5 minutes massage/stimulate, 10 minutes suction/expression and repeat. The cups max out at 6oz so if you pump more than that in a session watch closely because they'll overflow back at the flange insert. The noise level, I can hear them if I'm in a quiet room. But you can talk over them & you don't notice them if you're grocery shopping around people or something. The charge on these also last 2 full days (roughly 12 pumps) for me.
I looked at the MomCozys, Lansinohs and Elvies for wearables. I chose these for the cost. I couldn't really justify spending $200-300. I got these on sale for $65 with coupons. Easily worth the investment! Plus they come with all kinds of extras; duck bills, membranes, flange inserts, extension straps for nursing bras, nipple rulers and 2 nice velvet bags. I hope they last, but so far I'm super happy with the purchase!
Amazing pumps for first time moms!!
Affordable.
Easy to use.
Easy to assemble.
Timer is lit and built in on pump.
Lightweight.
Spill-proof.
Discreetly small in size compared to other brands.
Extra parts are free: bra strap, brush, type-c cable, 24mm and 27mm flanges and storage bags.
Only 4 parts to clean! and the milk collector opens up completely that makes it easy to clean.
Charging port is a Type-C! which means i can charge it on-the-go through my phone charger and power bank.
I am a mom of 3 breastfed kids. My eldest is now 8 and my youngest is 2 months old.
I used the more expensive wearable breast pumps for my older kids.
I did not realize how much inconvenience i had with my old pump until i tried MomMed.
My old pump is heavier and bulky.
I've spent at least $30 on flextubes for my old pump every 3 months.
Spent an extra $50 for the 27mm flanged milk container for my old pump. It came in free for MomMed.
I have to maneuver the milk collection chamber skillfully to avoid leaking breastmilk for my old pump.
It's harder to clean my old pump. The brush it came with does not reach the inside nooks and crannies of the milk collection chamber.
This comes as a set of two which is much better than buying one individual one as some others are sold as. For using around the house or on the go I want to be pumping both sides at once, not just doing one then the other. If you’re only mainly breastfeeding from one side though I can see how one would be better (so you can just empty the one that didn’t get fed from). However if you’re exclusively pumping or pumping both sides, having two makes it much faster.
You can’t be doing strenuous activity while you’re attached to these. They’re best for light housework or if you’re just wanting to pump and not be hooked up to a machine. Definitely can’t be making large movements.
The buttons are located on the top so you can adjust it easily while it’s attached to you. Personally I did find the buttons take some getting used to. You need to long press the power button to turn it on and off, but short press the power button to switch between different modes. Then there are 12 levels in each mode that it can be adjusted to with the plus and minus buttons.
Easier and more comfortable to wear if you get a larger bra to help secure these in place. They will be noticeable but not as bad if you’re wearing a baggier shirt or sweatshirt.
These portable pumps are a good option if you’re needing more freedom while pumping (like tending to another child or wanting to do work). Definitely allows you to have more freedom while multitasking and you don’t have to fiddle with the tubes that are attached to plug in pumps.
I absolutely love this pump! It comes in handy for when I’m working or trying to get stuff done around the house. Don’t be fooled by the size because it actually holds a good amount of milk during each pump it fits 10 ounces total. I did have to order different size flanges because the ones that come with it are way too big but overall I like it. I do wish it was a little more quiet because it is somewhat loud but not obnoxiously loud.
I absolutely love this pump! It empties me every time and is so convenient. I can pump while getting things done around the house instead of being stuck in one place. It’s comfortable, easy to use, and has made my breastfeeding journey so much easier. Highly recommend!
Although I haven’t used it but it looks so strong and durable I will give a better review when I finally use it. Thank you
