  2. Overall good buy. 5 Star Review

    I like that Maymom has a flange size that spectra themself don't carry. Better fit means less pain during pumping for me. What i don't like is that the yellow adapter is very difficult to remove when i'm trying to wash the parts.

    Bought these as the size of the flanges which comes with the spectra pump are too big. No more pain while pumping. Fast delivery too!

    Very impressed with the quick delivery.
    However, It would be great if you could text me when you almost reach. Perhaps 10 mins before you reach. Otherwise please provide notification about the delivery status.
    Because I was in the meeting when the delivery reaches my office.
    Thanks! Have a nice day!
