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)

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

Works great for what its intended for.

I’m assuming I’ve just received the wrong item somehow because these are definitely not made for the Spectra and are not the flanges pictured. I’ve included 3 pictures comparing what I received with my current Spectra flanges. As you can see, these are MUCH smaller and the hook up to attach the suction tubing is completely different. My Spectra flange is pictured on the right and this product is on the left (in two of the pictures) and then they are swapped around in the third picture (sorry about that). I’m hoping an easy return will fix this and I’ll receive the correct parts this time. I will update my review.

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.

Perfect fit for my Spectra S2

Loved them for about a month, then they cracked. I only pump once a day too so not over use and I take great care of them. :(

Thank you for saving my milk supply! I was so nervous it was diminishing and all it took was finding the right flange size! Great quality, fits perfectly on my spectra 2, maymom is the best!! thank you for accommodating those of us who are petitely endowed :)

Just like the Spectra flanges. If youre pumping and not getting anything out but still left with full breasts, your flange is probably too big. If youre using the standard 24mm honestly its probably too big. You have to measure the nipple only, just the little button, then add a few mm to it. I was having an awful time pumping, kept feeling numb, starting getting less and less milk but constantly felt my letdown forcefully. I measured my nipple finally and after trying the 19mm first, seemed to find a perfect fit here. Your areola should not be going into the flange! Thanks maymom!

Compatible with spectra pump! Going down a bit from the factory size is alot more comfortable!

I have gotten several knockoff flanges as Im trying to find my best fit. My only complaint is at least I cannot personally see any numbers indicating the size they are. I can figure it out, but I have to closely compare. I wish it were just written on there. Otherwise great product
