Super gut. Meine Pumpe funktioniert wieder. Die Saugkraft ließ extrem nach und dank den neuem O-Ring funktioniert alles wieder und ich muss mir keine neue kaufen.

Encaja perfectamente y funciona bien. Tardó poco en llegar. Es la única opción que he encontrado para el extractor porque en Medela hay que comprar la bomba entera.

Zonder o-ring trekt de kolf niet vacuüm

When I use my pump, I realised that I lost o-ring and couldn’t use pump at all. So I wanted to get it ASAP. Then I found this product, made me very happy. Oder immediately. The product came so quick and perfect replacement. I couldn’t find something like this any other place, so very happy!
