Very bad experience. My Momcozy Double S12 Pro Wearable Electric Breast Pump stopped working after about two months. I have only used it twice.
One of the pumps continuously displays the charging icon even after it has been disconnected from the charger, and it will not turn on at all.
The other pump continuously vibrates as if it is running, but there is no suction and none of the display lights turn on. I am also unable to turn either pump off. I have tried pressing and holding the power button for an extended period, but it did not resolve the issue.

The best wearable pump
This pump has been my bestie since Day 1! Literally! I first started using the s12 pro in the hospital a day after giving birth and it produced a great amount of colostrum. Since then there’s not a day that has gone by without me using this pump, it is my most trusted pump, I get a great output with it and it doesn’t hurt! Comfy and hands free, I’d highly recommend this pump to FTM like me!

Love Love Love, except when in public
The absolute best thing about this pump is its battery life. I can probably go two days between charges! The design is very comfortable and quiet. My family and I don't even notice it. It has nine suction levels and three suction modes. It has a quick and fast option, a mixture, and a full-on suction mode to stimulate a real nursing session. The only reason I'm taking a star away is its design. It is not discreet to wear in public at all. And cleaning the parts is a little tedious.

Do not recommend.
These are horrible. No matter what I do, they leak milk everywhere. I spent about 5 minutes making sure they were secure and the second I move, the silicone moves and milk leaks everywhere.

Momcozy S12 Pro
A nice breast pump. Helps remove milk well but should not be compared to direct breastfeeding. All in all, it does its job quite alright.

Not as good as I was expecting.
First few uses I was impressed as a pumping mom.
But after that both Momcozy pumps went down from 50ml collected to as much as 10ml from both pumps. I have tried few times, then gave up and using my bottle pumps which are less convenient but I am collecting at least 50-80ml per pumping session. In my opinion S12 Pro was literally waste of money.
