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)

Good comfort

I’ll take it since there aren’t a ton of options when you don’t fit the standard flanges that come with every pump, but they do leak if you’re not careful. A rubber gasket would go a long way to seal the top. If I lean too far forward because my toddler needs something, I can feel milk dripping off the side of the collection bottles.

These are great. I usually use another brand but I couldn’t find the 17mm in that brand. These work great with my Spectra S2 and NeNe Supply parts. I’ve used them every day for months now and they are still in perfect condition. My nipples can’t say the same…

Awesome alternative for my spectra!

Once I got properly sized and ordered these pumping became a lot less stressful! They fit on my Spectra perfectly and have worked without a hitch since they arrived!

I pumped for a year with the wrong sized flanges because I was too cheap to buy the correct size. Totally regret that! No discomfort pumping with these vs when I was using 24 mm ones. Can’t really tell if they helped increase production but it certainly didn’t decrease it!! It is weird how smaller flanges are more expensive but oh well. Worth it!

The first pair I bought had clearly been used (the packaging was ripped, there was grime on the flanges) and not cleaned which is just not sanitary for any baby. I returned those and got a new set. Second set was unopened and clean. They work just fine, just beware you may have to buy multiple until you get an unused pair. It’s hard to find 17 mm flanges otherwise I would’ve tried from a different brand given the first pair I bought.

I needed a smaller flange size but unfortunately Spectra did not make 17mm. These work PERFECTLY with my Spectra S1 and have been so much more comfortable than the 24mm flanges the pump came with.

I finally realized that medium size clothing and average bra size didn’t equate to average flange size. I thought using the smaller of the two flange sizes that came with the spectra was good enough, but Legendairy lactation pills said 90% of their customers use 19-20mm flanges! What difference switching from 24mm to 17mm made! Each pumping session went from 0.25-1oz on each side to 2-3oz each. Not sure if it’s flange or the combo of flange and Legendairy pills, but this desperate mama is grateful! The only downside is the shields are a bit small, so the pumping session may leak if not careful. But production is so much better with the smaller flanges, so a slight loss is trivial.

I ordered these and they came used in a ziplock bag with dried white milk remnants. Absolutely disgusting. Nowhere did it mention sending used parts. I expected brand new from a sealed bag.
