MaymomWide-Mouth Milk Storage Collection Bottle with SureSeal Sealing Disk; Compatible with Spectra/Motif Luna/Ameda MYA/Bellababy Pumps. Can Replace Spectra S1 S2 Bottles, 6 pc (4.7Oz/140mL, 6pc)

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.

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 versatilityFinal 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!

I bought these to go with my Spectra S1 since the pump only came with one set of bottles to use. These fit the flanges perfectly and they hold a little more than 5oz if needed. I have not had any issues with leaking and they seem to hold up well on the go. My only complaint is that I used pen on the lid to label the date and it did not come off clean as the description says. I just use them to pump and then pour into bags anyways but that feature was misleading. Otherwise they were a great price and a great option for additional bottles for my pump.

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!

Bought these to use with my spectra flanges and I love them! They fit perfectly and stay on. And I love that after I pump I can just place the top on it and place in the fridge for storage!

So I bought these bottles because I was exclusively pumping for the first several months of my daughter's life and I needed extra bottles to connect to the pump, store, and cut down on dishes. These worked great! They are a good price, easy to wash, great for storing. The only issue that I had is the inaccurate measurements.I was underproducing so every little fraction of an ounce was important to me (for accuracy of feedings as well as keeping track of production). The 1 and 2oz markings are wrong. If you pour 1oz into these bottles, it measures around 1.25oz. Same with 2oz. But once you get to 4oz it is accurate. I'm not sure how this got missed, maybe it's just the bottles that I got specifically but it was annoying and a pretty easy fix for the manufacturer. Also, the option to write on the lid is great, but just know that if you heat the bottles before you wipe the pen off, it will permanently stain.Hope this helps!

** Works with Baby Buddha breast pump **I bought this so I could have extra milk bottles for my Baby Buddha breast pump for work. Comes with six bottles that all have lids. They are easy to clean, are plastic, hold 4.7 oz, leak proof, and super durable. I've been using them now for 3 months and have no issues. I'm sure you can freeze the bottle but I haven't done that so can't say anything about it. I would buy these again for the simplicity and durability.

Maymom has always given me just what I needed. We used this topper to “hack” Philips Avent bottles - we wanted glass bottles but found the Lanisoh nipples to be a better gradual shape, so this collar fit the Avent glass bottles and the Lanisoh nipples! Perfect workaround.
