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 Michael Jackson

These are much much much better than than the bottles that came with the spectra pump. The feel sturdier and they're longer so they balance on my thighs when I pump cross legged so I don't have to hold the pumps up with my hands anymore. I used to have to change bottles half way through and leak everywhere. These bottles hold twice as much so I don't have to anymore. They're also much better storage bottles than what I was using before (just baby bottles). The seal on the lid helps keep in the milk in case I knock them over. Since they're such great storage bottles, too, I'm going to buy another pack of 4 so I have enough to keep using them for pumping and storage.
