2X 17 mm Maymom Wide Neck Pump Parts Compatible with Spectra S1/S2 Pumps; Incl Wide Mouth Flanges; Not Original Spectra Flange; Replaces Spectra Shield (Two Small Flanges)

I really like that it worked with my spectra s2

I have purchased multiple different flange sizes from Maymom for my Spectra S1 plus. While I am SO glad they offer smaller sizes than even Spectra offers - these actually dont screw on correctly to the spectra bottles and every Maymom flange Ive tried results in milk leaking everywhere . Its super frustrating and its a significant amount of milk. Unless you use it sitting perfectly still and are super careful when you remove the pump after a session, you will spill milk everywhere. Ive tried the 17mm, 19mm, and 21mm and ultimately while the smaller sizes have helped me out with pump out, the milk leakage is terribly frustrating and disappointing. Ive looked closely and when you twist the flange onto the bottle, it looks like it is slightly crooked. Ive tried all my spectra bottles as my pump came with four. Unless there is another part Im supposed to have to make it twist on correctly, be prepared to leak milk over everything! :/

This is the brand my lactation consultant recommended, great quality product so far. Had no idea knowing nipple size is so crucial to take into account while pumping - turns out Im 17mm, much smaller than what breast pumps come with by default. Tell every mom you know! The standard flange size is TOO LARGE for most women, its not average at all - which can be detrimental to milk supply.

Highly recommend that you measure yourself before buying. I was in pain because I had been using 28 and 30mm turns out I was 17mm!!

Awesome alternative for my spectra!

These work well. With is being pretty clear it’s easy to get your nipple lined up in the flange. If you’ve got elastic nipples these aren’t going to be long enough for you. Ive been using my pair for 3+ months and haven’t had any issues. Cleans easily enough with the right brush and nice to just pop in the brezza sterilizer.

I’ve went back and forth between Maymom and Nene supply and discovered I prefer Maymom more. One thing is the consistent breast shield size. I purchased the 17mm but have large boobs (before even BFing) and was pleasantly surprised that the shields were bigger than the 19mm from Nene. Way more comfy!

Would purchase again

I have a spectra breadt pump but I didnt realize until my lactation consultant sized me that my nipples are 17 and 15 mm. I was using a size 21 mm flange because thats the smallest size that spectra offers. Im thankful that maymom offers these products so I can size down and be more comfortable amd get better milk output. Im getting more ounces of milk for my second baby and I think the correct flange sizing has helped. I have even have a freezer stash this time compared to when I struggled to provide for my previous child. Thanks maymom!

Used with my spectra and had no issues with it
