Me: I have one of your kits for the symphony, and the membrane and protective cap smell like mildew. I have sanitized them twice according to the directions, and they still smell. Medela Lady: You said you had the kit for the symphony model, was that the one with the Lactina parts as well. Me: Yes that is correct. Medela Lady: That smell is from the rubber seals on the Lactina part. It is normal and will go away over time. Me: Oh... Medela Lady: Yes we get this call a lot.
So I guess I never had a reason to be concerned, but I do find it odd that they would sell a part which smells like mildew when it is new.
