High-Quality and Essential for Pump Maintenance!
These replacement duckbill valves for wearable breast pumps are fantastic! They fit perfectly and have restored the suction power to my pump, making it feel like new. The material is durable, easy to clean, and lasts through multiple uses without losing its shape. Having spare parts is essential for busy moms, and these replacements are a great value for the quality. Highly recommend for anyone needing to refresh their pump’s performance!

My pump is working like new again!
I was having trouble with my Lansinoh wearable discreet duo pumps, one was not suctioning on a side! I ordered these and they work like brand new again! They are exactly the same as what came with my pumps. I would definitely recommend if you feel like your pumps aren’t working like they should!

Good quality
Fits my mom cozy s12 perfectly and good quality material. I recommend lubricating the flange with some coconut oil or nipple cream before use. It did rub against my nipple and cause some cracking because it’s brand new silicone and has a grip on it

Life changing and doesn’t cost an arm and a leg while having the same effect.
I spent $60 on a name brand and these work better than those. I can buy two of these for the price of one while also getting the same fit on my spectra.

A must have for second time moms
Preparing for breastfeeding with a rambunctious toddler I knew I was going to need more help. I wanted to try out a hands free pump but didn’t want it to be my main pump through insurance. I hopped on Amazon to find a reasonably priced one and found this one. I couldn’t be happier with the purchase. The suction works well, it’s easy to use and clean and holds over 6 ounces on each side. Be careful with the suction, start off slow I made the mistake of putting it on too high. I have been thoroughly impressed and although I can’t compare it to the “fancier” versions I am so happy I have gotten the hang of hands free pumping and it’s an absolutely game changer especially for Moms of multiples who always have their hands full!

Great replacement
I was a little skeptical when I initially purchased these as they seemed a little smaller than the original and the material didn’t feel as durable but they fit great and have not leaked on me so far.
