Great for spare parts
Love having an extra pack of these for additional pump parts if one breaks or has to be cleaned. Fit perfect with my current pump
Mauvaise qualité
J’ai acheté ces pièces de remplacement pour mon tire-lait MomCozy S9 Pro (disait être compatible). Bien que les pièces entrent dans le tire-lait, le produit est trop épais, de mauvaise qualité et incompatible, la machine ne peut pas fonctionner avec ces pièces à l’intérieur. Il vaut mieux acheter les pièces de rechange originales pour ne pas avoir de problèmes !
Fits my momcozy
Fits my momcozy pumps. Good quality.
Not transparent
Fits ok , kinda hard to get in and out of the flange.The worst part is it is 0% transparent . Cannot see anything so positioning is very difficult. Would not re-purchase
Flanges
These fit my pump Perfectly
As expected
Soft silicone flange insert. Fits in my medela personal flex fit 24mm flanges. Comfortable, wish they were transparent to see and adjust positioning easier while using but overall has made pumping more comfortable.
Does not work for S9 pro.. donât know why it was advertised as such
Donât buy it.
Good quality
Good quality fit perfect in my momcozy
Muy buenas las valvulas, el material se ve y se siente de calidad.
No compatible con todos los extractores
Donât bother if you have the momcozy it doesnât fit properly so the suction is useless. I can normally pump in about 10-15 mins but with the new parts after 10 minutes I had only a few drops. Absolute waste of money
Not sure why itâs even advertised as being compatible when itâs not even close. And I tried to make a return since itâs unused and itâs not eligible for return and I canât get through to any customer service for help. So, I guess Iâm stuck with this pump part that doesnât work and I canât get a refund. Awesome customer serviceâ¦. Not
I’m always a little nervous to order a part that is compatable with another brand, but these duck bills fit my MomCozy pump PERFECTLY at such and affordable price!
