Can you place parts in automatic sterilizer/dryer?

unhappy- broken button after 2 months
Ive had the pump for 2 months and the power button has already broken.

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.

Comfortable, hands-free and easy to use
“Very comfortable and easy to use. The suction is strong yet gentle, and it fits well inside the bra, which makes pumping hands-free and convenient. It’s lightweight, quiet, and easy to clean. I use it daily and it has been very helpful for feeding my baby.”

Super produit
J'ai utilisé ce produit pour mes 2 allaitement et ca m'a bien servit lors des repas en famille, entre amis, ou juste les déplacements médecin/sage-femme. Je recommande les produits de la marque Mom Cozy. Pour avoir ensuite testé le M5 je n'ai rien à dire !!

A true game changer!!
This pump truly is the ultimate MVP for your pumping journey! After trying a hospital grade pump AND a hand pump after delivering my son, I was truly discouraged by the amount of discomfort I was feeling and lack of output. Once I had tried my momcozy s12 pro, i had so much more confidence and control with my experience. As a first time mom, I would recommend this pump over and over. Truly so comfortable and the settings are easy to understand and maximized my output early on. They even send you a flange sizing chart that was perfectly accurate!
