Maymom Pump Parts Compatible with Spectra S2 S1 9 Plus Breastpump, 24mm Flange Valve Tubing Backflow Protector, Not Original Spectra S2 S1 Replacement Pump Parts

These parts work great with my spectra S2 pump. I have had no issues using them.

These are extremely comparable to the Spectra pump parts. I actually cannot tell a difference between these and the Spectra ones except for the brand name on the side of them. I have repurchased these because I liked them so much.

We love this brand. The spare pump set is so much cheaper than the Spectra brand replacements and honestly you can't tell the difference. We pump a lot for our twins so having extra parts was a must. So glad I went with this brand.

This is the second set I’ve bought to use with my Spectra pump. Everything you need minus the bottles!

These parts work. They are NOT as good as the Spectra brand parts, however, they are a more affordable alternative. In my experience, the flanges leak where they attach to the bottles. The duck bill valves are a TIGHT fit and you have to do some yanking (which causes stretching) to remove them. Also, the back flow protectors easily slip out of the flanges. They do WORK, however, they are NOT the same quality as Spectra. If you’re looking to pinch pennies then I would recommend.

I have been struggling with pumping enough milk for my 9 month old for daycare. My milk has fallen drastically. I decided to buy new pump parts for my pump and found these on Amazon.I have had these for about 2.5 days now and what a difference in the amount of milk I am pumping!!I have been lucky to get even 2 ounces out of my right breast (my usual was 6-8 ounces). I pumped 6.5 ounces out of my left breast this morning!!So far these pieces have saved my journey with breastfeeding my baby.

I had no idea you had to replace pump parts! These worked perfect on my spectra2. Came with the white duckbill and a second pair of blue ones! One less part to need to buy later!

Loved the products I received.(I have the Ames’s Mya breast pump) The box included an extra pair of duckbills which was awesome!Was nervous about purchasing hit was happy I did! They work perfectly with my pump and having two sets keeps me from washing parts all day! (Which is AMAZING!)I’d definitely recommend for Ameda Mya users!(Btw: I love having the case for the duckbills!)
