Great quality product
Just fantastic it's priety quiet when in use extremely comfortable IV only used it about 5 times so far but I'm very pleased I have tried several other pumps and I think this one's the best yet although there was another pump IV used and it was close is it worth buying and the money I'd say yes.

Would recommend
Very expensive and it looks like the replacement plastic parts are expensive also, but honestly this has been a godsend for my wife and I. I would highly recommend.

Amazing breast pump
I’ve been really impressed with the double hands-free Mum Cozy breast pump. The overall quality of the product is excellent — it feels well made and durable, and even the carry case it comes with is great quality and looks really stylish. I also liked that it came with different size flanges, so you can choose what works best for you. Charging is really straightforward, and once charged, the pumps last quite a while. They’re also comfortable to wear, which makes such a difference when you’re using them regularly. The only downside I’ve found is that if you’re moving around a lot and happen to bend over, milk can sometimes spill out from the top. There isn’t a plug or cover for the opening, which can be frustrating. But as long as you stay upright, it works perfectly. Overall, it’s a high-quality, reliable pump that makes expressing so much easier and more convenient.

No regrets
I transitioned from primarily using the Spectra S2 to the Momcozy M5, and the difference is incredible. For one, the silicone flanges are much more comfortable than hard plastic. Even using the same size, for the same duration, I get better output from the Momcozy. It is generally more convenient being hands-free; I can hold my baby or wash dishes or do work while pumping, rather than holding bulky pumps in place and not being able to move further than a few feet. The only downsides I have found are 1) they are much louder than my spectra, so it can get fairly irritating to listen to when I am already sleep deprived. And 2) the battery part of the pumps can get quite warm after 20-ish minutes of pumping. I've only been using them for 2 weeks, so I will be keeping an eye on the battery life and seeing if it heating up is affecting it at all.

Exclusively pumping
I was on YouTube and reviewed many wearable pumps on the market, the choice and variety is very overwhelming. However, I chose Mum Cozi due to its reputation and reliability. I am really glad I picked these. The price is accessible they are user-friendly wash friendly and I was able to Pump around 27 ounces within 24 hours using these pumps which was sufficient for my newborn. I have been exclusively expressing milk for five months using these pumps only and I am very happy with the outcome I initially wanted to use these in between feeds however I found that exclusive pumping alone Worked better for me and the baby I would highly recommend these pumps. my final reason for these pumps were because they were not Bluetooth made me feel that they would not be harmful to my breasts with the radio waves, et cetera. The customer service for Mum Cozi were great. I found that my pump was leaking and when I rang customer service in giving them my Amazon order number they replaced them within a couple of days with a five minute conversation on the phone. The customer service was fantastic and gave me reassurance that I picked the right brand. There are more expensive wearable pumps on the market and cheaper ones however this brand for me worked perfectly. Milk production varies from person to person therefore I recommend milk Production tea , regularly pumping with a pump schedule, not skipping pump sessions, drinking plenty of water eating protein filled diets and resting where possible, as long as you are eating and drinking well your milk Production should increase over time. There are many settings on the pumps there is the quick pump and there’s a long suction motion, strength of the pumps go up to level nine which I have never been up to (it’s too painful), I initially started using the pumps on level six with combination suction motion however my skin felt very sensitive after therefore I reduced the suction to level four and three, which was manageable and didn’t make my skin feel sensitive. The beauty of these pumps is that they allowed me to exclusively breastfeed my child for five months with freezer supply also. At the end when I watched lots of videos I realise that washing them after every pump session was paramount therefore the main and final reason I bought these in particular were due to the least number of parts that needed to be washed every day after every session. I have to say they’re very easy to wash Multiple times a day letting them dry and then putting them back together very straightforward.

Niet kopen! Kolf lekt en de pomp doet het na 2 maanden minder goed. Heb spijt dat ik hier €300 voor heb betaald. Ze zijn ontzettend zwaar en je moet letterlijk blijven zitten tijdens het kolven. Ook kan je geen contact krijgen met de verkoper.

Questo tiralatte è stato un salvavita per la mia routine da mamma! Completamente a mani libere, lo indosso nel reggiseno e mi muovo liberamente mentre tiro il latte, comodissimo a casa. La potenza di aspirazione è davvero ottima e grazie alle 3 modalità e 9 livelli, ho trovato subito il ritmo giusto per me. Si sente che è pensato per aumentare la produzione di latte senza stress né dolore. La flangia è super morbida e si adatta perfettamente, senza fastidi. Inoltre è silenzioso e discreto. 🔋 La batteria dura a lungo (circa 6 sessioni) e il display LED è comodissimo. Anche il lavaggio è facile: solo 4 parti da pulire. ✅ In sintesi: pratico, efficace, comodo e bello da vedere. Lo ricomprerei altre 10 volte! Super consigliato a tutte le mamme.
