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 Jon Cherian

I am really disappointed that these are one of the only options of milk storage bottles that are compatible with my Spectra S1.1. There lid looks bulky and has a rough ridge around the top. It is also not aesthetically pleasing to look at, as it does not "match.”2. There is an inner gasket on the lid that is difficult to take out to clean. I am afraid it will start to mold if I don’t spend extra time cleaning that area. As an almost exclusive pumper I would prefer something that was designed better. The Spectra bottle lids do fit and are easier to clean (see photo).3. These bottles will not fit in the bottle holder built in to the Spectra pump - which is inconvenient if you are planning on pumping it the car or somewhere where a table is not accessible.4. As you could see when I took the lid off, a little bit of milk spilled out. They do not leak, however, when the lid is twisted on.
