Maymom 8 Count Duckbill Valves Compatible with Spectra S1 S2 9 Plus Dew 350 Not Original Spectra Pump Parts S2 Accessories Replace Valve (White)

I used these for my Spectra Gold and they worked amazing. They were very easy to take off and clean. Will definitely buy again with the next baby

Wow! These were awesome to ween our little one off the nipple. Fit perfectly onto our glass Phillips bottles. I hate clutter and this eliminated more cups in the cabinet. Very cost effective compared to buying all new cups and can connect on glass that I already own. I like the variety as well with the straw attachments for water. So happy I bought these!

Better than the name brand replacement parts. Love this brand and the product works better than spectra brand.

These flanges work well as a replacement for the ones that came with my Spectra S1. They are a little bit longer than the originals, which means their suction is a little stronger. I wouldn't recommend using it with the Medela manual pump as the suction is too strong and doesn't let the milk out.

They fit well on the Spectra s2 but they have terrible suction. Every time I pumped, I had milk left that wasn't expressed, and I started getting clogged ducts because it never got everything out. And I'm sure I would ahve lost supply if I had kept using them for more than 3 days. On top of that, it was taking 50-60 minutes to pull out what should have the 20-25.

I love these.They work so amazing with my pump.Even they're not exactly made for my pump.They still work phenomenal there pretty cheap.They are so heavy, which is really nice.Cause they are not wearing down anywhere near as quickly as my others love them. They have been such a lifesaver , and they make it feel like my pump gets more suction with them

I've purchased these about 5 times now. On average, I'd say 3 are duds (the opening is too big), so make sure you examine them closely before using!

Worked well with spectra and motif luna wall pumps for me!!
