desertcart.com : Momcozy Nipple Ruler for Flange Sizing, Soft & Flexible Silicone Measurement Tool for Breast Pump Sizing, Compatible with Momcozy, Medela, Spectra, Lansinoh, Easy to Use for Comfortable Pumping : Baby

Review: Confy, easy, silent - It's super quiet, comfy to wear, and the size is just right for walking around. I could move around easily, but some moves might make it slip. I'm giving it 5 stars; it's exactly what I wanted for the price and quality.
Review: Best handless pump - I am a momcozy user for life. I replaced my old M5 with this one and I really like the overall design and function of the handless pumps. It is nice being able to use them at work and move around. Definitely worth the price. The suction isn't bad either. I think it is pretty strong and gets the vast majority of the milk out. If you need to get inside of the pump due to liquid getting inside, there are four small screws under the rubber flaps on the motor part. It is easy to unscrew to let dry out before tossing the pump doe to an error.
