Great!!!!!
These worked great for my spectra pump. I actually really liked that they were pink and not white. They had almost a gritty texture which was also nice and easier to grip when wet to assemble pumps.

Quality replacement parts for pump
I use these in my spectra s2 pump and they work great, fit perfectly and are durable quality and duration. Have repurchased many times

Works great
Got these for my spectra S1 and my output remained unchanged (in a good way lol) and I like that they match my pump 🤣

Great replacement parts
I decided to start buying colored sets of these parts so I know which ones are newest as im rotating the pieces when I have to replace. I feel like these replacement parts are actually higher quality than the standard spectra ones. They feel more durable and like they’ll last a lot longer. Ive already had to toss so many spectra valves since they no longer had a good seal.

Very good quality
These work very well! I also love how the color matches my spectra 2.

Spectra replacement
These are amazing replacement parts. Definitely worth buying and will repurchase if needed. They help so well with milk supply when you get replacements. They were so easy to use and clean and fit the spectra perfectly

Great product!
Love these!! I exclusively pumped for a view months while working on baby’s latch issues. These helped keep my pump working great and efficiently!

Repuestos de muy buena calidad, no notĂ© cambios en el rendimiento de mi extractor, pero tal vez las cambiĂ© antes de tiempo. Si las volverĂa a comprar.
