Review: Do not sterlize this - My original one got melted in the sterlizer so in I ordered a new one. Do not sterlize this, it cannot handle high temperatures.
Review: Great for spectra 1 and 2. I had both and these worked as great replacement parts. Much needed for longer term pumping. I typically switched these out every 3-4 months to help keep supply up
