desertcart.com : Maymom 2x17 mm Wide Neck Pump Parts Compatible with Spectra S1/S2 Pumps; Incl Wide Mouth Flanges; Not Original Spectra Flange Shield (Two Small Flanges) : Baby

Review: Better than flange inserts - Compatible with my spectra and fit great! Way better than flange inserts to go with the flanges that come standard with the pump.
Review: Love love love - I love Maymom products! They have yet to disappoint me. I started my nursing pumping journey when I had my son back in January and met with an IBCLC who was able to correctly size me for flanges. Turns out I am a 13 and a 15 MM so the standard size flanges that came with my spectra breast pump clearly didn’t fit. When I was looking at flange sizes that would fit me maymom popped up and I ordered them. They have been incredible. They wash amazing and are very durable. The quality is great. I’ve used these now every day since January. I’ve ordered multiple sets so I have four sets to use during the day and rotate. They’ve held up amazing. I sterilize everything everyday still so even being exposed to the high heat, they’ve held up extremely well. I 100% will recommend this brand for replacement pump parts to anybody
