Nenesupply 4 pc Duckbill Valves Compatible with Medela and Avent Pumps Not Original Medela Pump Parts Work with Medela Pump in Style Medela Symphony Replace Medela Valve Membrane and Avent Valve

I have an avent manual pump and own a Medela double electric pump in style and these work perfect for both! I was tired of cleaning the small membranes that the Medela originally comes with and felt I had to replace every month due to suction. And after a long while it was time to replace my avent duckbill. These are easier to clean than the membranes that originally come with Medela pump and have a great seal. These aren't as thick as the duckbills that originally come with the avent pump wich is what helps them be compatible with the Medela pump. If you have the older pump in style and done with cleaning the small membranes then you need these.

Highly recommend these to replace the native Spectra brand duckbills! They have the special tab to remove them from the pump, which I think greatly contributes to how well they hold up (the spectra ones you have to yank or pry off and I think it seriously shortens their lifespan). Not to mention they are less than half the price for twice as many!! I pump an average of 3hours/day and these easily lasted almost four months, which is unheard of for duckbills! I would rotate daily between the two pairs. I finally just chucked them not because of any signs of wear or need of replacement, but because I have put so many hours on them. HIGHLY recommend!!!

I bought these in a desperate attempt to get better suction and more durable vales than the flimsy little ones that come with the Medela pumps. These definitely met my expectations! I instantly noticed better output while I was pumping. They are easy to clean, and hold up better than the other valves. My only complaint is that they make a noise, kind of like a quacking duck, during pumping. It's not terribly loud, but loud enough that I hoped my male co-workers couldn't hear it on the other side of my office wall. None-the-less, I would not go back to the other kind of valve once I discovered these!

I bought these because I love the little duckbills that sometimes come with my motif Luna replacement parts. But sometimes I get regular duckbills, and they seem to wear out extremely quickly with how often I pump. I saw these suggested as an alternative and I love them. The pull tab is not something I use often but it’s nice to have. They seem to have great suction and don’t wear out nearly as quickly as the regular duck bills.

I was struggling to find pump parts for my Philips Advent Manual pump and these work perfectly.

It’s so hard to get replacement parts for the Avent pump but these are great! They fit well and my output has been steady since I switched the original duckbills out for these.

They get the job done but the quality is not a good as the OEM. I find these these leaks while I'm pumping.

I’m obsessed with these things, and sharing how much I love them with all the pumping moms I know! They work great with my Medela PISA, and I really feel like I’ve seen an increase in production since I started using them. I also love how much easier they are to get off when washing! As a new mom, I’m all about convenience and saving time, so I can do things like snuggle my babe and SLEEP! I love that these valves mean less time pumping and washing the dreaded pump parts!
