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 Maurice Hurd

I really like these except for something g very very important. The bottle wouldn’t seal properly to the flange (which are compatible) after a couple weeks of use. I lost about eight ounces of milk because it crashed to the floor. In the following weeks, the lids (that came WITH the bottles) stopped sealing and would just pop off and the rubber inside one lid came off completely. No, two of them. So even if I’m careful pumping the lids don’t seal.Im going to buy another set and hope it’s just a fluke. But either way be careful I don’t want anyone else losing milk.
