## Customer Reviews

### ⭐ Bad quality
*by R***. on February 17, 2025*

Diaphragm are too thick and smaller than the original momcozy ones. I had to push them in hard, and it made my pumps leak milk all over my bra. Duckbills were good for like a week and already getting loose. I have the v1 model.

### ⭐ To thick
*by S***A on September 20, 2024*

The silicone is pretty thick so it is a little difficult to click the back piece on. It also affects the suction horribly. I’m not an over supplier by any means but what I got out in a pump was no where near my normal especially after not pumping for 6 hours prior.
