Maymom MyFit Classic 28mm Shield Compatible w Maymom Widemouth Connector Not Original Spectra S2 Accessories Spectra S1 Not Original Spectra Pump Parts Spectra Flange

Perfect for my spectra! I wish more pumps had better size changes. Since spectra doesn’t make the smaller sizes, I bought this so I could buy a properly sized breast shield. This fits the spectra perfectly and I get a decent pump sessions with it. Very easy to clean and sterilize though. I ended up ordering a second set to help support washing/sterilizing downtime. Highly recommend!!

Excellent quality, works well for my Spectra allowing me to use not only Maymom flanges but LacTeck flanges as well.

Maymom adapter initially APPEARS to fit Mila's Keeper wide neck glass storage bottles but it's DECEIVING - the issue is that it untwists with ZERO resistance, as though it never screwed all the way down even though it is screwed alllll the way down (even tried removing the silicone bottle sleeve). However, good news, Idaho Jones, Nenesupply, and Pumpmom adapters/connectors all screwed into Mila's Keeper securely (esp Pumpmom was really snug) and would allow you to use a flange of your choice and still pump directly into the storage bottle.

These fit perfectly on my spectra bottles. I utilize lacteck flanges with these adapters and they’re great.

I got these to use Pumpin pals and lacteck flanges with my spectra and they work perfectly!

Love it, comfortable and suitable

Works well with the Spectra pump, you can use your Medela shields. I like this because I can use it in my hands free bra instead of the one-piece from Spectra. I am happy with my purchase

I ordered these after needing to size up from my 13mm (also Maymom). I loved my 13mm--much more comfortable than the 28mm and 24mm my pump came with--but they've become too small. I first ordered 17mm by accident, so I ordered these 15mm flanges. They're better than the 13s, but seem too big and look basically identical to the 17mm, though much larger than the 13mm. I even looked at the sizing on them to double check, but they do say 15mm. I haven't tried actually measuring them, though. I'm giving them 4 stars because they're still better than what I had and are great quality, but not 5 stars because I'm not sure they're actually the right size.
