Loved these at first but after only a week of constant use they keep falling off mid pump, one won't stay on it literally pops off like it's to small.

I replaced my factory valves with these and didn't look back. These last longer and work better. I have a motiff luna. Thanks for attention.

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…

These are flimsy and do not do the job. They seemed to have made my supply drop. Wish I would not have purchased them. May not be BPA-free.

I love these duckbills, even more than the actual spectra ones! They arrived as they should (no gaps in the center). They do wear out fairly quickly but I do a lot of pumping so I expected that. But considering I received brand new spectra duckbills with gaps in them I consider this a huge win especially for the price!

I do NOT recommend these. I’ve exclusively pumped for three babies, so I am no stranger to the pump and pump parts. These are the worst valves I’ve used. They worked okay for a very short period, and now they fall off constantly. They should last longer than a week or two.

I have Spectra S2 and my valve had a tear in it so had to buy a replacement. Spectra and all other stores seem to sell ONE pair for $13, while this has 3 pairs for $8.50. Can't beat that. I love that it's blue and for some reason that makes me happy. :) I've had this for 4 months now, pumping 5 times a day and have had NO ISSUES or tears. I had 2 pairs of original spectra valves and they both ended up having tears. Not sure if it speaks to the quality, or if I was being extra cautious to avoid…

Love these for my spectra S2 pump. Significantly cheaper than brand name but same functionality. I like the different colors so I can make note of when I changed parts based on color.

Love the color option so I can tell which ones I’ve already replaced. Easier to remove than the white ones, I like these much better than Spectra valves and they’re much more affordable. Three pairs of this brand for less than the price of one pair of Spectra brand

The work but if you want something quiet these are not it. They make a loud sound every time the pump pushes air instead of sucking. Sounds like someone making farting sounds withtheir mouth.

Usually as far as flanges and diaphragms I LOVE maymom! Not with these blue valves. They have no suction. I went from pumping 45 ounces in 24 hours without any extra stimulation, heat etc to 31 ounces with heat, massage, compression in 24 hours. I tried for two and a half days and my milk output was tanking. I was pumping 35-40 minutes and closer intervals trying for milk.I went back to the valves I’ve had for 3 months using 8 times a day. I had 2 ounces in 8 minutes on each side without even…

I prefer these over the name brand duckbills. As an EP I use these quite often. I like that there is a bit of the texture to them so I can get them on and off to clean/sterilize easier. They last a long time. I know I’m supposed to change them out monthly but I’m going on 2 months on the same duckbills with no loss in suction.
