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)

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....

I’ve had a set of these I used for my son, saved them and used them again for my daughter - the first set broke - however it was out through MANY HOURS of pumping. So I put them through the ringer and after 2 years of pumping I had to buy another set! I’d say they are extremely durable and long lasting which is why I bought another set because I know it will last me a long time!

I guess I am not the average but I was so happy to find a replacement for my spectra pump parts that actually fit what I needed! They are a little hard to clean the inside but not impossible. i actually bought these twice as I pumped for a while and needed to replace! Would buy again if needed.

Im still doing some trial and error with my sizing but Im so thankful this brand makes a wide variety of smaller sizes. It was perfectly compatible with my Spectra S2

I had to leave a review because maybe it could help some mums out there. I was using the spectras 20mm and 21mm, I was experiencing sensitivity & pain. I had read about the importance of flange size so I decided to purchase these in 18mm (for references my nipple size pre pumping is 15mm and post pumping 17mm). Well long story short, wow, the difference is just wow. Don’t give up and find your flange size, it will drastically change your pumping for the better. No more pain, yay.

These work awesome with my Spectra 2. Being able to get a smaller sized flange was a game changer for me and pumping. No more pain because of the incorrect size and it helped with my output. I went on the website to find the printable measuring tool to get myself the correct size. I couldn’t be happier that someone makes a variety of sizes and it’s a decent price.

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!

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…

Just as good as the ones that come with your pump but way better! It’s so nice to have one that fits properly, it has definitely helped with comfort and getting milk out! And yes it does fit on the spectra pump’s!

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! :/
