Review on Nenesupply 9Oz Wide Mouth Feeding And Storage Bottle Compatible With Spectra S2, S1, And 9 Plus Pumps - Includes Nipple, Sealing Disc, And Compatible With Spectra S2 Accessories And Pump Parts by Joel Gumbiner

The bottles by themselves are great. It's so nice having a cheap, 9oz option to use with my Spectra S1 pump and is compatible with the lids. The bottles seem nice enough and are light and have held up well from repeated washings, use, etc.My problem is with the lids. The lids are all one piece (or so I thought) - except there is a small piece of rubber lining on the inside that is nearly impossible to take out without pliers. I noticed this morning that there was a ton of mold growing underneath this little rubber piece and was thoroughly grossed out. I'm throwing out all of these lids immediately. If you use these bottles, I do not recommend using the lids! Or at the bare minimum - be sure to take out that rubber piece and clean it each time!
