Review: Spectra pump part - These work perfect for the Spectra pump. Great value for your money. Easy to take apart and put together.
Review: Pumping? Just buy them now - I accidentally snapped the funnel on my Spectra. I didn't have any extra. I ordered these. They came quickly and were just what I needed. As someone who pumped and was in desperate need of these, I would recommend just buying an extra set now instead of going through the panic of trying to find a set or a replacement quickly! It is too easy to snap them.
