MomcozyWearable Milk Collection Cups with Storage Bags (5 oz), Direct-to-Bag Breast Milk Bag Combo, Breast Pump Parts for Momcozy V1 Pro/V2 Pro/V1/V2 Pump & Most Electric Breast Pumps, 2 Pack

I’m absolutely obsessed with these. I just went back to work after maternity leave and was worried about my pumping journey and having to clean a million parts while at work but this has truly saved my life. Minimal parts, easy for traveling, and the suction is just as strong as the original collection cups. These are incredible!

Likes:-Allows me to pump directly to a bag while I’m at work-minimal cleaning required in between pump sessions, compared to other wearable pumps-comfortable-connects to most all pumps including my spectra and other Momcozy pumps like the v1 or v2Dislikes:-cups for the bags to sit in are pretty large and non discreet-separate the bag at the bottom before pumping or it will leak-price of bags $$$My take: loved this option for work so I’m not having to clean a ton of large pump parts at the office, however I did leak my first time because the bag separates and expands at the bottom and mine was stuck so it limited how much milk it could hold and overflowed.Suggestions:I’d love to see reusable silicone bag options where someone could buy like 6-8 of them for the workday to fill and keep in a fridge and wash once home with minimal cleaning between pump sessions at the office. Overall a great option! A little pricey though since you have to provide your own pump. Momcozy keep innovating this industry! Love it.

A lot of parts to clean but ideally these are great for on the go and they are compatible with a lot of pumps not just the momcozy. I like the idea of pumping directly into the bag for convenience but the downside is you don’t actually know how much you’re getting since bag measuring isn’t accurate and these are a hard read.

Works great. It's a nice to be able to pump directly into a bag (just make sure the bag is pushed all the way in). It's also nice that all the replacement parts come together.

I am a smaller chested mom even while breastfeeding and these did not suction well enough to get a good output. With that said, my supply has gone from approximately 60 oz per day to about 8 oz per day. I’ve had to acquire donor milk to keep my baby fed. I would not recommend.

I love that these milk collectors can fit onto most pumps. They’re so much easier to put on than the pump parts that came with my spectra and they don’t need a special bra to be able to wear, however, I have found that for some reason, it doesn’t empty me quite as well as the other set of flanges. But just barely. Overall, they’re great to have, especially if you’re exclusively pumping.

Love and I attach it to my spectra s1 making me more free and snuggle my baby.

So I’ve used this a few times and while I love it, there are some cons…1) if the cup is not on PERFECTLY, the device will suck in air and once the bag is full, it’s full. It doesn’t matter if it’s air or milk. On my first attempt, the bag was full and when I removed the cup, milk poured out everywhere because the bag filled up with air before it was finished emptying me.2) It is very difficult to tell when the bag is full. The directions say to stop pumping at 5 oz, but when the bag is properly installed, the measurements on the bag are facing towards your body, so you can’t tell when 5 oz has been reached.I have used it with my Momcozy V2 and I’ve used the adapter with my Medela Pump in Style and I did not notice a dip in output when using it with my Medela pump. I find that the measurements for volume are pretty accurate compared to my Medela bottles that I pump in when using my Medela pump. The bags are a little expensive so I try to not use them when truly on the go so I don’t have to pour milk from cups to bottles and spill milk in my car.I also have not found replacement parts for the valve and duckbill, so that’s slightly concerning as well.
