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

I got the product maybe a month ago or so and I was loving it, helped pull more milk & was working for me but I keep the plastic part in my work bag at night So I can pump in the morning at work and my bad fell off a box it was sitting on not even 2 ft off the ground and was the smallest drop ever and the entire piece shattered into like 7 pieces with the slightest drop which kind of sucks since it was an expensive part but other than it seeming it broke kind of easy the part was great!

Works great for what its intended for.

This brand has never let me down and I appreciate that they offer so many flange sizes. They work great with my spectra.

Flanges fit right where I needed it.

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!

Perfect fit! Finally I’m not in pain when pumping! The flanges are not as big as OEM spectra but they actually fit my large breast better by being shorter

I was so excited to actually use a flange size that was right for me but when this arrived there was a hole in the package and the pink duckbill pieces were missing…. Flange works great but sucks to pay for something and not get all parts!

Flange fits me well (please note to buyers: make sure you get sized before purchasing). Works really well with my Spectra S2. Note: where the backflow connects to the flange has a small space but it doesnt have suction loss issues. Flange is easy to clean and fits in my to-go drying rack.

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
