Double Hands-Free Wearable Breast Pump Parts 19mm Milk Collector Cup Compatible with Momcozy S9 Pro|S12 Pro Breastpump Incl 19mm Flange Use with S9 Pro|S12 Pro Parts/Accessories Replacement

My S12 pumps didn’t work well with these. My breasts hurt very bad. Item is not returnable so I spent the money for nothing. There is no way to contact the vendor for reimbursement.

I didn’t have high expectations to be honest just because of the price & it being an unknown brand. However they actually work great! I use them with my Zommee Z1 pump and I get the same amount of milk as I would with the regular cups! They are very comfortable to wear and they don’t take away from the suction, plus it’s super convenient to use hands free!

I’m trying to return this item. I have tried multiple times it only gives me the option for trouble shoot. And it goes straight into “continue shopping”

Love love love. These are one of the best pumps I own and I am absolutely in love with them

Been using Momcozy pumps for a total of 9 months. I’ve used the S12 and S12 Pro and never had an issue until using this set of cups.I am using the correct flange type and these cups say they are compatible but they hurt when I use them.When attempting a return there were no options available except troubleshooting. Do not waste your money.

Don't waste your money. Doesn't fit the s12pro motor snugly so you don't get adequate suction. You can actually hear air leak out while pumping.

Bought when one of my cups broke for momcozy s12 pro. Does not plug in effectively and caused issue with the pump itself because of it.
