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)

Same quality as spectra flanges.

Awesome alternative for my spectra!

Hated spending so much for the 17 mm as I had already recently bought the 20mm, but it is SO WORTH IT. I have short, flat nipples and with the standard 24 mm flanges, my poor nips always felt terribly bruised. I would get tears in my eyes if my children or husband accidentally bumped my chest. According to the ‘measure after pumping’ rule and using a mm sizing guide, the 20mm should fit but I must have nips that swell to fit all available space. With these, my areola isn’t being painfully sucked into the flange. No more bruised painful feeling! I exclusively pump and use these for 4 30 minute pumping sessions every day. They have held up very well, no signs of wear and are easy to clean. If you’re on the fence, buy them! I actually might be able to go a size smaller but I’m happy with these. Thanks Maymom!

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.

Fits great on spectra pumps. No leaks

I brought this product for my BestFriend to use and when we got the package it was open and had been used, there was somebody’s breast milk inside the tube pump part, it was gross not I have to send it back and I’m waiting for a replacement

These fit on my spectra no problem! Wish I’d bought them earlier to avoid some of the problems I had pumping

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.

I was hoping to increase my supply with a smaller flange but it did not help. However the flange works just like the Spectra one. No issues with the flange.

This is my 3rd purchase of successively smaller flanges. I use a motif luna which came with 24 and 28 mm flanges. I bought their 21 mm (too big) and maymoms 19 mm (also too big). These 17 mm are pulling the least areaola into the tube of any yet, so I think this is where Ill stay. When I purchased the 19 mm maymom, I bought the whole replacement set as I read some reviews that said that the spectra parts did not fit seamlessly with the maymom flanges. The 17 mm flanges work perfectly with that set, as does my pump. Someone mentioned in a review that it doesnt say the size on the flange- it does. If you look down the tube, it is imprinted onto the plastic at the end. Very happy with this purchase.
