Maymom Wide Neck Breastmilk Collection n Storage Bottle 5.4 oz; Re-markable SureSeal Disc. Fits Spectra S2 Spectra S1 9 Plus.

So, I grabbed a pack of these Maymom 4.7oz bottles a while back, the 6-pack, because I needed something that would play nice with my Spectra pump. And honestly, they've been pretty decent, especially when I was just getting the hang of pumping. They screw right onto my Spectra flanges, no problem, which was a relief – didn't want to be fumbling around with adapters or anything. What I really appreciate is that the lids, these SureSeal things they call them, actually seal. Like, really well. I’ve had them tipped over in the fridge (thanks to my own clumsiness mostly) and no leaks, which is a win. I’d just pump, cap them, and into the cold they’d go. That 4.5-ounceish size is fine for me (small mom 4ft 10) I am not getting a ton of milk per session, so it feels like a good, manageable amount without wasting a giant bottle. Pros: They genuinely fit my Spectra. The box also says they work with Motif Luna, Ameda MYA, and Bellababy, so that’s handy to know. Those sealing disks are legit. No crying over spilled milk, literally. For starting out, six bottles felt like a good number to rotate through. Cons: The biggest thing is just the size. That 4.7oz (or 140mL, whatever) will fill up fast once my milk eventually comes in. I will have to look for bigger bottles down the road. So, if you’re already pumping a lot or expecting to, you might find yourself wanting to size up pretty soon. Bottom line? They are getting me through those initial pumping days without a hitch. They’re reliable for what they are, especially with the pump compatibility and the tight seals. Just know that for many folks, including me, they’re probably a stepping stone to larger capacity bottles down the road.

These bottles fit smoothly into a pumping and storage workflow. The wide-mouth design makes filling and cleaning straightforward, and the sealing disks help reduce leaks during storage. Measurements are easy to read and consistent across bottles. They stack well in the refrigerator and are convenient for rotating milk throughout the day. Pros: compatible with common pumps, easy to clean, leak-resistant design Cons: glass alternatives may be preferred by some users Note: This is not medical advice. Please consult with your pediatrician or lactation consultant about this product and the instructions on how to use this for any further information.

I started using these Avent Wide Neck Breastmilk Collection & Storage Bottles with my Spectra S2, and I couldn’t be happier with the choice. The 9oz size is perfect for my needs, and the Remarkable SureSeal Disc keeps everything secure without any leaks or mess. These bottles are super easy to use and clean, and they fit perfectly with my Spectra pump—no need for extra adapters or parts. The wide neck makes pouring milk into storage bags so much easier, and I love how sturdy they feel. It’s clear they’re designed with durability in mind. Pros: ✔️ Fits seamlessly with Spectra S2 pump (no leaks!) ✔️ 9oz size is perfect for collection and storage ✔️ Easy to clean and doesn’t get cloudy with repeated use ✔️ The SureSeal Disc keeps everything secure ✔️ Works with Avent Classic Natural Bottle too for extra versatility Final Thoughts: If you’re using a Spectra pump and need reliable collection bottles, these are a must. They work perfectly, are easy to use, and make my pumping sessions smoother every time. Definitely my go-to for storage and collection now!

Easy to clean and a good size for me. When I pump, I get ~5-6 oz which is more than our usual bottles hold (my baby only drinks ~3oz at a time and is using 4 oz bottles). I especially like that it’s compatible with avent bottles so after portioning some of it into our usual bottle, I can just add the bottle nipple on top of this storage container and save myself some bottle washing. It also fits better in our thermos for easy warming on the go (the Philip avent bottle is wider and doesn’t fit in our Yeti water bottle with hot water). I also like that I can write the date on the lid with a ballpoint pen, but have found it doesn’t always remove completely. It may be more user error, since it does say to remove ink before washing, and sometimes my husband doesn’t notice before loading up the bottle washer. But I have found it stains even from just hot water (when I’m rinsing in the sink to remove the ink).

These bottles worked wonderful for pumping and feedings. They are leak proof and have a good capacity along with fitting well in diaper bags. You get exactly what you pay for worth the price!

These bottles are made from a very thick plastic. The numbers and tick marks on the side of the bottle are raised plastic instead of ink. It’s difficult to see inside the bottle due to the material thickness and color - the plastic is much more white than clear. They are very sturdy and fit the Spectra pump flanges. The rubber lid caps can be removed and replaced with a nipple. The Lansinoh or Pigeon nipples fit well. Overall a good value and works as hoped with my pump flanges and the bottle nipples that I use.

Perfect collections cups! Def worth the money.

I originally bought these to just be storage, but I realized that the lansinoh nipple fits in the cap perfectly so I have also been using them as extra bottles! That was an exciting surprise, and even though it seems that the measurements are slightly off (by a quarter-half ounce or so) these were a great purchase!
