Maymom Wide-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 love these! I plan to use them to transport pumped milk home from work but at the moment I am using them to store pumped milk in the fridge before dividing and freezing. I love the silicone in the lid - it creates an awesome seal but is also super easy to pop out and in for cleaning. A standard bottle brush fits these bottles well so they're a easy to clean. They are marked to hold 4.7 oz but you could really fit 5 oz in each if you don't need to see the exact measurements. They fit my Spectra S1 flanges directly and also standard wide mouth bottle lids/nipples (I've tried both Avent Natural and Nanobebe with success). No issues sterilizing or heating in a bottle warmer.

These are great, I like them a lot better than the Spectra bottles. Markings are clear and easy to read (unlike the clear markings on the Spectra bottles) and they seal well and attach to the flanges without any issue. They also include a little silicone ring that you can use if they are loose. My favorite part is the caps you can write on, it works great with a regular ball point pen and comes off with just a quick scrub with the scrubby side of a sponge. So convenient and easy, much better than using scotch tape like I was with the spectra bottles. If there was one thing I'd change, I wish it had markings on two sides so you can more easily see how much you have as you're pumping. It seems like the markings are always facing my body as I pump so I can't see them without pausing pumping.

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.

Okay I actually LOVE these! Before I would use painters tape to write the date of when I pumped but now I can write it on the silicone top and it erases when I’m done. Wish I got these sooner!

Great affordable alternative to spectra collection and storage cups. Fit the spectra flanges as well. My only con is that if you are storing in fridge and using a bottle warmer, the item is made of plastic. The item is bpa free but it still makes me uncomfortable to put plastic in a steam warmer. So I ended up switching to glass storage bottles but still use this to pump into since glass is too heavy to sit on my breasts. Otherwise great function depending on use.

** 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.

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!

So good and convenient, love this

So happy that these fit my spectra pump! Now I don’t have to be running to wash the bottles I had

S’adapte bien a mon tire-lait spectra, parfait

Purchased to use with my spectra S2 pump and they work perfectly! The lids also work for the spectra bottles so were the perfect addition to my breast feeding supplies and eased the burden of having to wash parts too frequently.
