Review on 6Ct White Maymom Duckbill Valves Compatible W/ Spectra S1, S2 & 9 Plus Dew Pumps - Not Original Parts by Christopher Holker

It's hard to show in the photo but pumping mom's know the pain in the butt a duck bill is with gaps so no suction is achieved.I am Very disappointed. I wanted to switch out all my pumping parts and saw this cute blue and was hesitant because it's not my normal. I have not even used these a week. They all are already gaping so you have very mild suction. It's not worth it. I had to go back to my duck bills that are old to pump with a stronger suction seal because any of the new ones are not working. Any pumping mom knows how important it is for these to be quality pieces. When i received these i saw the gaps but because they were softer feeling material compared to my regular spectra ones I still gave it a try. Now i have to wait for better ones or go to the store and actually pick up good ones. It's a good thing i didn't toss my old ones in the rubbish bin before i tried these. Please incorporate more quality control in product before it's shipped out to consumers.
