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 work and fit with my motif luna but with one of them I have to press and twist the diaphragm into it so hard it feels like Im going to break it. The other fits just fine so there is something different about the way it was produced that gave one of them a smaller hole. Hopefully it doesnt break my diaphragm soon or wear away the connection point so that I lose suction on other flanges.

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. :(

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

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!

The subject says it all. One of the two pack leaks from the connection to the Spectra bottle. I couldn’t figure out what was happening at first but lost a bunch of milk because of this. I will buy again because I can’t find the size I need elsewhere but am disappointed.

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.

Product was great and delivered on time. I am really happy with the order. It was great to find flanges in sizes different than what spectra offers.

I hate that no pumps on the market come with smaller than 20mm options for those of us with smaller nipples. Hurts like hell having to use the wrong size, so I’m really glad I stumbled upon these! Was hesitant because they were off brand for my spectra, but was desperate enough to try and the price wasn’t terrible. They work perfectly! No issues at all. A good buy if you are looking at these and need them.

Fits spectra bottles & my adaptors for my Medela bottles

Unfortunately I was not able to use this. It’s my second set I have bought. I use my other set with my travel pump. I love these products but before using it cracked. I was hand washing it and noticed it was cracked on the tunnel. Super sad since these aren’t exactly cheap....
