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 Carta Gutierrez

I bought these bottles to use with my spectra pump and for transporting breastmilk to and from work. So far they work pretty well. I filled them to the brim and they hold about 5 ounces. I’m also able to use them with the medela double contoured ice pack. I say double contoured because with the single contoured ice pack I’m not able to zip up that bag, but with the double contoured I’m able to fit four bottles and zip up at the bag. see the pics I deducted one star because on a couple of bottles the silicone ring keeps falling out when I clean them or open them. No matter how hard I push it in, the ring keeps falling out. And the instructions say to keep the silicone ring in place leak free protection. Still, I’ve had no issues with leaks and I’ve used the bottles daily for about a week. I did have an issue with my order in that I only received four bottles, though the listing and the box said six bottles. But I reached out to the seller and they replied within the same day and sent me a new pack of six bottles immediately. So the customer service was great.
