## Description

This product has a variety of models, which can change the size of the "breast milk channel" on the cover of the breast pump, so as to be suitable for mothers with different nipple sizes, help to improve the breast feeding efficiency and increase the pumping capacity, and make mothers more comfortable in the process of breast feeding.

Review: Había estado usando unos adaptadores que eran más plásticos y sentía molestia, al rato de usarlos me picaba y se notaba que generaban calor....en cambio estos adaptadores son más finos y cómodos, es un material diferente, aunque son algo más caros en comparación a otros, valen mucho la pena, me encantaron y son fáciles de usar, los recomiendo mucho
Review: It works exactly as it should! - No complaints for this product! It is affordable and practical! I’ve had no problems whatsoever with it.

No complaints for this product! It is affordable and practical! I’ve had no problems whatsoever with it.

### ⭐ Does not work and no refund
*by M***E on August 16, 2024*

These dramatically lower the suction on your pump to the point it doesn’t actually work anymore. When you let Amazon know it doesn’t work as advertised they won’t let you return them. Save your money. These are garbage.
