NENESUPPLY9oz 4 Count Wide Neck Mouth Breastmilk Storage Bottle Breast Pump Bottles Use for Pumping with Spectra S1 S2 9 Plus Breast Pumps. Replace Spectra Bottles for Pumping Breastmilk Collection

Why did you pick this product vs others?:Love these bottles, they’re compatible with my spectra pump and great for an breastmilk oversupplier or for someone who stores milk in the fridge over several days.

I use these daily for pumping. Work perfectly with my Spectra pump and I love that they hold 9+ ounces so I don’t have to stop pumping to empty the bottle half way through. Plus the lids are it nice for storing milk in the fridge.

These fit great on my Spectra. They have held up well being washed many times in the dishwasher.

I’m really pleased with this product! It arrived promptly and was in excellent condition. It’s just as described, and the quality is outstanding. It works perfectly and has made a real difference. I’m thrilled with my purchase and feel it’s worth every penny.I’d highly recommend this to anyone looking for something dependable and high-quality. I’ll definitely buy again!

I purchased these to supplement my the containers that came with my Spectra breast pump. I pumped directly into these containers and used them for short-term milk storage and transport. There are two sizes (both pictured in relation to the Spectra bottle). The smaller size is smaller than the Spectra container and the larger size is a full 8 ounces. I actually had both sizes. I used the small ones to pump directly into and combined my output into the larger containers.I exclusively pumped for over a year and had lots of pumping supplies that I replaced frequently. These were a great value. I preferred these to the Spectra bottles for a number of reasons, the ounce markers were in color on these bottles making it infinitely easier to tell how much you pumped or were pouring. It's a small thing, but when you are fumbling with storage containers in the middle of the night, the last thing you want to do is squint and guess about the ounces because of the stupid clear containers.The lids on these are key. They are pretty darn leak proof when used with these containers. I used the lids on the spectra containers and while they work - it's an exact science and I ended up with a diaper bag full of milk and a ticked off baby. Never again. These lids are great on these containers. One caveat, there is a spill proof plastic sealing ring in the lid that makes the seal. Repeated washings and using loosens these up and they can fall out. If they fall out, these lids aren't leak proof anymore - MAKE SURE THE SEAL IS IN PLACE!All in all, I am a big fan of these and use them for lunches now that I've stopped pumping. Just one note - MAKE SURE THE SEAL IS IN PLACE.

Love that these fit onto the spectra. Cute shape and the small size makes me feel better about being a just-wnougher lol. Though the measurements are definitely off. These cups will say 3.5oz but when I pour into original spectra cups they say 4oz

As a mama with an oversupply, these bottles connect to my Spectra pump and make it so I don’t have to swap bottles out halfway through a pumping session. They don’t leak and are easy to clean. Love them!

If you are an over-supplier like me, you need all the extra space you can get. I purchased these bottles with hopes of less clogged ducts and more volume to fill while pumping. I am happy to report they have done just that and I have had them less than a day! They are compatible with the Spectra S1 pump and easy to set up!
