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)

Good Little Bottles for Getting Started with Pumping
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.

Great extra bottles for Spectra
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.

Works with spectra
These are really nice for working moms. With my baby still eating roughly every two hours sometimes more these are nice for when I’m at work to help keep my supply up. She doesn’t like the taste of frozen milk so these come in handy for storing my milk for her while I’m gone. They are compatible with spectra. The only thing I don’t like is that they aren’t completely see through like most baby bottles but they get the job done.

I use these for my spectra s2 pump & the fit perfectly (no need for adaptor). They’re especially handy when you’re double-pumping, as the bottles can go straight to the fridge. I have not put them in the freezer though, so cannot attest how they will hold up.

Buen producto, calidad regular. Si es compatible con extractores spectra solo que el material plástico de las botellas se ve y se fuente algo barato. Es plástico opaco, es difícil distinguir el marcaje de las onzas. Por el precio pudiera ser mejor.
